How to use an Engineer's Scale (or Engineer's Ruler)

If you need to measure distances on a plan set or map using an engineer's scale and have been confused how one works, this video will show you how to do it.

[@kentvandervelden]

Thank you for the video. I've had one of those rulers for years and never realized how to use it. So simple

[@Xerodude]

Like some have said, great video. It's clear and concise to someone who is learning the beginning of scales.

[@Pterocarpous]

I've had one of these for ages - now I understand how it's intended 2b used. Thank you for explaining so well!

[@bradystraughan9751]

I know this video is old (it's 2019 when I'm writing this) but it just saved my life for an engineering test coming up! Thank you for the explanation, despite the out of focus!!!!

[@neptune145]

DUDE THIS IS WHAT I NEEDED I GOT AN MECHANICAL RULER

[@HowToWithGEO]

No problem. Thanks for watching.

[@xxoutlaw2022xx]

Thanks for the video, very clear and concise. Ignore the haters....sure it was blurry at parts but still able to fully understand the principle. Appreciate the time and effort!

[@HowToWithGEO]

Thank you so much for the post. I've been working on my focus.

[@dilbyjones]

@@HowToWithGEO lol these things are true

[@HockeyDudet]

Thank you thank you!!! This video was so clear and easy to understand. It is much appreciated. :)

[@jcalbain]

Yes it was blurry at some points but the explanation was clear and to the point. I really don't see how some can't understand it even with the blurry parts. Yes a clear video is nice, but I can see exactly what you're doing and these things happen sometimes. Thanks for helping. Don't mind the people complaining keep posting videos.

[@HowToWithGEO]

I do really need a new camera. Thanks for the post. I will get one soon.

[@bigbonedandbroken-kristinn4354]

Great info, but it would have been nice if it were not so blurry!

[@jasondaidone5427]

exactly what I needed

[@Engineersupply]

Nicely done, and well explained !

[@MarkMcPeak5895]

Thanks for the knowledge. Wish you'd have explained the 20:1 ratio a little more.

[@Paintingwithrita]

10:1 - means 1 inch is equal to 10 feet (on drafting designs etc.) or 10 miles, if you're looking at a map with that scaling. Maps usually have a key that says 1 inch = X miles - so you can use this ruler to know how many miles you're looking at on the map. 20:1 - means 1 inch is equal to 20 feet (on drafting designs etc.) or 20 miles, 30:1 - means 1 inch is equal to 30 feet (on drafting designs etc.) or 30 miles, and so on. So, rather than using a regular ruler and getting a distance of 4 3/4 inches and having to multiple it by the miles/inch, you would just use the side of the ruler that matches to the scale of that map (or drawing), and if it was 50 miles/inch, then instead of seeing 4 3/4 inches you would see a marking for 237.5 miles on the 50 side of the ruler.

[@HowToWithGEO]

Your scale may be a Metric scale. Go an measure it's entire length, from first mark to last mark. If it is 30 cm long then it is a metric scale. If it's a foot long, or 12 inches, then it's an english scale.

[@jameshenry2457]

Not only out of focus, but ruler is reversed and upside down. Yeah I know...I can figure out what he's trying to show, But, It would have been just as easy to present it correctly. And yes, DO pay attention to the people complaining. That's how you improve your presentations.

[@SpiritSwarm]

Top twat

[@HowToWithGEO]

Yes, common comment. sorry about that. I do need to get new camera.

[@2pakalypse]

thanks for the vid very helpful but i kinda got confused since i use the metric system but was still good

[@daisyivetteestrada3348]

Thank you!!!!

[@Julius-yf1hp]

Does an engineer's ruler only measure feet? For example, 18' 6" inches, how is it measured? Can those six inches be measured

[@Abdur_Rahman176]

Dear Sir, please give me the link where from i can buy this scale?

[@missourigal]

I wish the video was blurry and hard to see.

[@barbarawondergem3374]

Miles are cool but do not give complete explanation as I'm sure most of us will be using for feet. So If you added an explanation of a random measurement of like 12'4" or 12'5" anyway something with inches, so we could understand how 10 segments breaks into 12 inches on this ruler. Just adding that would make your presentation complete and the best easy to understand thats out there.Thanks. (Im doing a parking lot site plan and the city traffic planner wants it drawn to 20 scale, not knowing anything about that, I have learned alot on here with all these videos....and this guy explains it very well... just the inches explained.)

[@DjdubS713]

thx dude

[@Abdur_Rahman176]

Dear Sir, how can i buy this scale? Please help me

[@TOASTuh]

Great video, but my professor hates it when we call it a "ruler" ;)

[@monkeyd.dragontherevolutio9544]

Was this recorded in a potato?

[@jodia7435]

Do I need glasses?? I don't see a thing.

[@nathanbirk878]

Very helpful. Thank you.

[@sadafmukhtar3290]

how long 1.5mm

[@lifeisgood070]

thank you. Now I know I must convert using this rule to measure centimeters. :(

[@jonathanrivera6807]

thanks

[@flammenwerfer9645]

FUCKING FOCUS GODDAMNIT DUDE!

[@desireeannelegaspi8468]

I want to learn more 😊😊

[@michellealonso2952]

20:1 scale in engineer scale

[@ModernGreaser]

This would be great if you could actually see it. It is too blurry to see anything.

[@angbender1521]

nice focus....by the way

[@brianspendlove430]

I've got to get my eyes checked

[@thatonemajin3578]

WHICH SIDE IS WHAT MEASURMENTS

[@jcalbain]

They aren't measurements per se they are increments. Eg, if you're using 1 increment for a mile then 4 increments (notches on the ruler) would be 4 miles. In between the 2nd and third notch would be 2 and a half miles. Its the same for other sides but if spaces are further apart then your drawing would be larger.

[@eleuterioalvarado9807]

gracias

[@HowToWithGEO]

Yes, I know. I like "scale" better myself. But many people don't know what the heck you are talking about is you say scale.

[@freddavis5544]

Unfocused objects give me headache

[@Daluke61]

Focus

[@Ninjanoodles78]

literally, focus problems. Video is blurry

[@marioprzepiora2224]

Can't see anything. Get a camera that can manually focus.

[@whitecloud620]

The subject is out of focus

[@sadafmukhtar3290]

plz guide me 1.5 mm

[@neptune145]

Syeda Noor that means millimeters

[@MadameNocnaMora]

First off please fix the focus on your camera as referencing to a blurry stick is hard to follow. Also use it in action. Using words like ratios and scales is already hard enough for us non engineering plebs. It'd be very beneficial if you slowly went through and demonstrated the concepts in action. "here's a building that is set to be 1" = 10' now let's see how it's drawn to a scale of 1" = 30', see how you can switch the sides of the ruler to help convert the numbers properly?"

[@timwoodworth236]

Blurry

[@stevenclark8533]

Not in focus

[@mamayake]

If you're going to talk about scales and rulers in ENGINEERING......USE PROPER FOCUS LENSES

[@Kolef88]

focus anyone?

[@jasminpuentes7121]

i have a

[@bestamerica]

' cannot watch this video... very bad blur focus with videocamera... try fix it clear focus and do again video

[@shawnofdadead1805]

Blurry AF...

[@59z2]

Do it over , out of focus.

[@joshb2904]

wow, low quality

[@mgray612]

Dang, how can you teach anyone anything when you can't even focus a video camera?

[@metaColin]

This video should be taken down. It's so out of focus it ends up being more confusing than clarifying.

[@joeghbi7558]

out of focus.

[@ZJohnnymnemonic2]

Filmed on a potato

[@jamesb9965]

This is about the worst presentation ever.

[@Xerodude]

Like some have said, great video. It's clear and concise to someone who is learning the beginning of scales.

[@jonathanrivera6807]

thanks

[@Artemis_simetrA]

was this filmed using a potato?
