About this worksheet

Weight and mass conversions use one fact: 1 pound is 16 ounces, 1 ton is 2,000 pounds and 1 kilogram is 1,000 grams. Each sheet has twenty measures, ten going to a smaller unit and ten to a larger one, in pounds, ounces, tons, kilograms and grams. Your child writes the new number on the line, with the unit already printed.

What your child will learn

  • Convert pounds, ounces and tons
  • Convert kilograms and grams
  • Multiply to go to a smaller unit and divide to go to a larger one

Common Core standard: 4.MD.A.1

Worked example

5 lb = 80 oz, because 5 × 16 = 80. And 3,000 g = 3 kg, because 3,000 ÷ 1,000 = 3.

Common mistake

Dividing when the answer should be in a smaller unit, so 5 lb becomes less than 5 oz.

Helpful hint

A smaller unit means more of them: multiply. A larger unit means fewer of them: divide.
