Measurement Conversions Lesson for Kids

Instructor: Carla Palomino
In this lesson, learn how to convert measurement units so no one can trick you when you go buy your favorite soda. Discover the basic rule for conversion and how to convert weight, length and volume units.

Measurement Conversion

Measurement is the action of measuring something. We can measure time, weight, height, temperature, length, speed, etc... We use measurement because life is so much easier when we know how tall we are, what time of day it is, how cold is it going to be, or how heavy our backpacks are.

Measurements can also be converted. Imagine you go to the store and ask for 15 feet of fabric to make your school football team flag. After cutting the fabric, the sales person tells you: 'here you have 5 yards. It costs $20'. You don't say anything but on your way out, you are thinking you told him 15 feet, why did he give you 5 yards? This is why: measures can be converted, 15 feet and 5 yards are exactly the same.

Basic Conversion Rule

Conversion may seem complicated but here is a trick that will help you convert any unit without any problem. The basic rule is:

If you need to convert from a LARGER unit to a SMALLER unit, MULTIPLY.

You will make the number bigger and multiplication is all about making numbers bigger. Here we convert one yardstick to three rulers:


Convert from a larger unit to a smaller unit
convert measurement 1


If you need to convert from a SMALLER unit to a LARGER unit, DIVIDE.

You will make the number smaller and, as you already know, division is all about making numbers smaller.

Convert Weight Measurements

Imagine your mom has been saying she needs to loose 3 pounds. How many ounces are there in 3 pounds?. We are converting from a larger unit to a smaller unit so we must multiply: 3 X 16 = 48 ounces.

From ounces to pounds, divide by 16. From pounds to tons, divide by 2000. From smaller to larger, divide.

From tons to pounds, multiply by 16. From pounds to ounces, multiply by 2000. From larger to smaller, multiply.

Convert Length Measurements

If your dad is 6 feet tall and you want to know his height in inches, multiply 6 x 12 = 72 inches.

From inches to feet, divide by 12. From feet to yards, divide by 3. From yards to miles, divide by 1760. Remember, from smaller to larger, divide.
