U.S. customary units: weight | 4th grade | Khan Academy

Would you measure the weight of your parents' car in ounces, pounds, or tons? Actually, you could measure in all three! However, you want to choose the unit that is most convenient in terms of numbers of units. Let's learn more.

Grade 4th on Khan Academy: 4th grade is the time to start really fine-tuning your arithmetic skills. Not only will you be a multi-digit addition and subtraction rockstar, but you'll extend the multiplication and division that you started in 3rd grade to several digits. You'll also discover that you sometimes have something left over (called a "remainder") when you divide. In 3rd grade you learned what a fraction is. Now you'll start adding, subtracting, multiplying, and comparing them. You'll also see how they relate to decimals. On other fronts, you'll learn how to convert between different units (which is super important when comparing the size and speed of robot unicorns in different countries) and continue your journey thinking about various shapes in two dimensions. Some of the foundational concepts of geometry (like lines, rays and angles) also get introduced. As always, we'll round this out with a healthy dose of applied word problems and explorations of number patterns and properties (including the ideas of factors, multiples and prime numbers). The fun must not stop! (Content was selected for this grade level based on a typical curriculum in the United States.)

[@yyubikirii661]

Also, metric is way easier than the customary way because customary has all thoses measures of how much is in that measurement and you have to remember them all but for metric, You use KHDUDCM (King Henry Died Usually Drinking Chocolate Milk) to measure and it is way easier!

[@gamemastershy1980]

Trena RBLX I live in Australia and the metric system only includes 2 measurements for mass called grams and kilograms

[@iisunny_parrot2797]

This is good thanks teacher for posting this as our homework.

[@Babu.Mani123]

You teach me a lot and learn a lot

[@m.helenavantzelfde7151]

I don’t think that newer generations should continue being taught this system. Metric is the way to go!

[@rushzei]

No its not

[@chrisxz7210]

im a newer generation but i want something that is better learning insteaed of everyone ignoring the words he says, no one likes math :/

[@zathanielW]

the metric what?

[@Cole_West]

Hey, pounds ounces and drams make sense in hexadecimal, and computers unterstand hex a lot better then base10, so maybe this is the way to go. Oh, and Russia has a unit called the pood, which is 16 kg. Kettlebells normally come in poods.

[@iisunny_parrot2797]

I don’t know metric but I agreee with u!

[@sadbreathing2716]

Thank you 😊

[@gooddeedsleadto7499]

Though I have used metric systems in my Engineering education, I still like American units measurement system or Imperial system, because it makes more sense to me.
