Read each problem. Write the answer.
Measuring words only stick when the number beside them is one the thing could really weigh or hold. These free printable worksheets pair every quantity with a container it fits — a sack of flour in kilograms, a carton of milk in milliliters — so the unit is never the odd part of the question.
If they get stuck

The answer key prints on a separate page.
The questions are the four a measuring lesson needs: how much is used and how much is left, how much several containers hold together, how much each one gets when a total is shared, and the same amount written in the other unit. That last one is 4.MD.A.1, where 3 kilograms and 200 grams has to become 3,200 grams before it can be compared with anything.
Each noun carries the band it can plausibly reach, so a parcel is weighed in hundreds of grams and a bag of sand in tens of kilograms. This is 3.MD.A.2 at the younger end and 4.MD.A.2 where the conversion appears.
One question off this sheet, worked a step at a time — with a sentence saying what just happened and why.
