How to Check if Your Scale is Accurate Without Calibration Weights (Using Coins)

This video shows you what you can do if you don't have calibration weights.
Buy Calibration Weights: amzn.to/3wf5y0o
Calibrating a scale without weights can be accomplished. All you need are a few coins to do the trick. This video guides you through the complete process, and you can also use the coins to also calibrate your scale with a little simple math.

Thank you. Simple, quick, and easy to remember. Interestingly, I've discovered that new nickels weigh differently than the old ones.

[@mrmatt7210]

The materials used in the manufacturing of coins have changed over the years and in doing such has also affected how much a coin weighs. For example Quarters made from 1873 through 1964 (1873-74 with arrows at the date) - 6.25 grams Copper nickel quarters made since 1965 - 5.67 grams 40% silver Bicentennial quarters (1976-S) - 5.75 grams

Thanks so much for this. Turns out my cheap scale is accurate

[@avirei98]

Yeah my scale is messed up and I feel like I got cheated I just ordered some official weights but they don't come in till Friday and I don't think I can wait a whole day just to weigh my product so trying to figure out how to recalibrate it without waiting, This has been incredibly useful thank you I saw somewhere else that said use 10 nickels for 50 mg but I'm like how accurate is that really?!

[@KJVism]

It really depends on the level of accuracy you need. I've weighed 4 different one euro coins that should weigh 7.5 grams each. They weighed between 7.5 and 7.39 grams. A huge difference when buying expensive commodities.

[@RobSomeKnowledge]

If in NEW condition, US coins are very precise on the weight, of course wear and tear will physically remove some material from the coins and then of course they will weigh less. However if you are buying very expensive material like precious metals, etc, then I would recommend you spend a few bucks and get an actual calibration weight set. They are literally less than $20, I have a set linked in the description.

[@al_kaloid]

@@RobSomeKnowledge The weight sets for under 20 bucks are nice for centigram or decigram scales, but analytical balances require E1 weights for proper calibration that cost at least a hundred bucks per weight. I just bought an old but beautiful Sartorius 1207 MP2 in pristine condition for a great price. Unfortunately the calibration weight required is an 80g E1. 80g weights aren't manufactured anymore, so I would have to buy at least 3 E1 weights, 4x20g would be even better to also adjust for linearity according to the service manual (despite the higher deviation). I'm actually thinking of going to a pharmacy and asking whether they could weigh my cheapo calibration weights on their analytical or maybe even semi micro analytical balance (doubt it) and just go from there. Can't really justify anything else since it's just a hobby, but I wanna know where I'm at with these cheapo weights.

[@waytoolazyy]

ik the guy below said this but i wanna put my 2 sense in anyway😝 i would only use newer coins made within the last 5 years

[@Rawteeth]

Thanks! This is super helpful!

[@Jay28u]

FYI - for those in the UK - A 1p coin weights 3.5g (an 8th of an oz) a 5p coin weighs 3.2 grams (a dirty thieving robbing B'stead 8th) a 2p coin weighs 7g or a quarter oz - handy to know when buying valuable substances in the UK (2:42)

[@RobSomeKnowledge]

Great info that I don’t have the experience to share, thanks!

[@adelataei8785]

Thanks a lot 😊

[@dewitubeX1]

I bought a 100g weight to calibrated and the nickel weighted 4.96g so im going to go with that the nickel i have is a little bit less than 5. When i put the 100g weight is still gives me 100g. Good video by the weight

[@RobSomeKnowledge]

👍🏼. Is it a newer nickel in great condition. Like less than 5 years old? The more a nickel circulates slowly small amounts of material will be removed affecting the weight. Calibration weights are definitely the way to go if you can spare the money for them

[@pupdog7374]

What was presented here is fine for the majority of folks. If someone wants a calibration method more presice, look elsewhere. Nice video.

[@RobSomeKnowledge]

Thanks! And well yeah, any method other than buying GOOD precision machined calibration weights isn't going to be very accurate down to the centigram, milligram or even smaller scale.

[@geminil2415]

But what if they aren't weighing so accurately what do you do???🤔

[@RobSomeKnowledge]

Most scales should have a calibration process, the exact procedure can vary by scale, so its best to lookup your exact scale model then add "calibration" and google it. Should be able to find something unless its some no name brand. But the basic process goes like this, you enter the scale into calibration mode. It will display a certain weight it wants put on the scale to calibrate. Some scales I have for example, ask for 100g and 200g. So then you place a calibration weight for the correct amount and hit a button to calibrate. You CAN do this with coins but its recommended to use actual calibration weights for most accuracy. Here's is a pretty good set of cheap calibration weights that I use: amzn.to/3XhAqKU

[@robertmazzola6882]

Very precise and clear great video, with the exception of what to do if your scale is not accurate

[@RobSomeKnowledge]

If your scale is not accurate then you need to run through a calibration process. This varies from scale to scale so I would refer to the manufacturer or manual for your specific scale. But the concept is basically you enter calibration mode. Then the scale will ask you to place a calibration weight for a certain amount of weight. Let’s say 100g for example. Then the scale will recalibrate based on that weight. If you want to be more precise it is definitely recommended to use actual calibration weights (like this amzn.to/3gdxbki ) if your scale needs calibration and not the coin method. However if you don’t need it super precise you could definitely use coins to calibrate it. Just make sure to use almost brand new coins so the weights are spot on, then just stack the coins until you get to the required calibration weight.

[@mr.redhookster8958]

Thanks for the video. I knew about the $1 but not about the coins

[@RobSomeKnowledge]

Aye I’m glad I could teach you something new!!

[@leannscott7309]

I already knew that I needed to know how to calibrate them

[@RobSomeKnowledge]

It’s different for every scale. You gotta find out how to get into the calibration mode then put the amount of weight they request on the plate, to calibrate

[@litsoccer3231]

[@meshiaaddis6460]

How do I fix my scales or if my scales are off, like if my scales read 3.6 for a nickel? It's 1.7 off so how do I fix this

[@RobSomeKnowledge]

If your scale is not accurate then you need to run through a calibration process. This varies from scale to scale so I would refer to the manufacturer or manual for your specific scale.

Just make sure to use almost brand new coins so the weights are spot on, then just stack the coins until you get to the required calibration weight. For example if you scale requires 100g of weight for calibration, you could stack 20 nickels since each nickel is 5.0g x 20 = 100g. Make sure that you are using modern day coins in like new or mint condition to rely on the weights. Older coins like nickels from the early 1900s have higher silver content, and earlier pennies have higher copper content, so they will not necessarily match the weights in this video. Again I highly recommend investing in a $20 or less set of calibration weights if precision is your goal.

[@rickkane8043]

If it is not accurate how you calibrate it?

[@TheYoutubeKid1]

Calibrate weights

[@coochiecrook7120]

So I put the penny on and it shows 2......I add another penny and it shows 5!? I add another penny and it shows 7....another penny and it shows 10! wtf

[@RobSomeKnowledge]

What’s the precision of your scale? How many decimal points does it have?

[@chellecole1124]

Your scale is set to measure to the gram. So something that weighs 2.5 or lower is going to show 2 grams. Something that weighs 2.6 is going to show as 3 grams. Change the weight to read to the tenth of a gram and problem solved.

[@chellecole1124]

So essentially the issue is that when you are putting the penny on the scale it is weighing 2.5 grams, and being rounded down to 2.0 g. When you add the second penny it is weighing 5.0 g, when you add the third, it is weighing 7.5 g, and rounding down to 7. When you add the 4th it weighs 10 g.

[@RobSomeKnowledge]

Yep, this exactly

[@3dtexan890]

You really need to check the dates on the coins. They are NOT all the same weight throughout the years. Just sayin'.

[@antoniomorales8515]

What if your scale is off though? This video is only showing if you’re scale is on point. Most people would expect their scale to be on point but this video is only showing how a scale already is when you buy it. But how do you fix it when it says a nickel weighs 4g?

[@RobSomeKnowledge]

If your scale is not accurate then you need to run through a calibration process. This varies from scale to scale so I would refer to the manufacturer or manual for your specific scale.

[@danielchrisronan2281]

If you want PRECISE measurements, then you're idea is wrong. Every coin gets dropped, stepped, rubbed on the concrete, etc... so not all coins weigh the same. I ran into this problem a while ago... Now I use calibration weights. 🤓

[@RobSomeKnowledge]

Which is why I say if you want it to be most precise to use coins in LiKE NEW condition. Even so, unless you are using a microgram scale, coins in new condition are good enough in most people’s use case. Also like I already said in the video yes calibrations weights are gonna be more precise, obviously. They’re literally manufactured for that purpose.
