These 4th grade measurement conversion worksheets are generated rather than scanned, which means you can print a different sheet every day of the week without paying for a subscription or running out of practice. The version loaded below opens with items in the shape of 2 yd = □ ft and 4.1 km = □ m; the key lists 6 and 4,100 next to their question numbers.
‘New set of problems’ opens the generator in its own tab. There you can change the problem count and turn the answer key on or off. ‘Print or save as PDF’ opens the print dialog — choose Save as PDF in the printer list to keep the file. The sheet fits US Letter and A4, and the answer key prints on its own page.
Metric conversions are all powers of ten, which makes them a decimal place-value exercise as much as a measurement one.
The reliable check is size: converting to a smaller unit always produces a bigger number. Children who apply that check before calculating rarely divide when they should multiply.
The conversions here use inches, feet, yards and miles and cover the units children meet in class rather than obscure ones, as the item 7 m = □ cm on this sheet shows.
Because each sheet is new, the child cannot rely on remembering a particular converted value.
These 4th grade measurement conversion worksheets are commonly aligned with the measurement and data strand for this grade, and the skill appears in most curricula somewhere around this point.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 2 yd = □ ft | 6 | Watch for: dropping the unit from the answer |
| 2 | 4.1 km = □ m | 4,100 | Check: losing a factor of ten in metric work |
| 3 | 5 hours = □ minutes | 300 | Look at: assuming metric and customary units interchange neatly |
| 4 | 4 yd = □ ft | 12 | Ask about: multiplying when division was needed |
| 5 | 7 m = □ cm | 700 | Watch for: using the wrong conversion factor |
| 6 | 4 minutes = □ seconds | 240 | Check: converting in two steps and rounding in the middle |
The item 4.1 km = □ m is worth doing slowly. The answer to 4.1 km = □ m is 4,100, and the route to it is the route every other problem on this sheet takes — which is why the sheet has 20 of them rather than one.
A good first problem to do together is 2 yd = □ ft, which comes out at 6. Do 2 yd = □ ft once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.
Keys are produced by the same code that produces the questions, so a mismatch between question and answer is not possible on these sheets.
The answer key is generated with the worksheet, not written by hand, so it always matches the sheet in front of you — 2 yd = □ ft is listed as 6, 4.1 km = □ m as 4,100, and so on down the page.
Portrait orientation is what the sheet is designed for. Landscape works but wastes about a third of the paper, so leave the orientation alone unless you have a reason.
Printing works the same on US Letter and A4, because the layout uses relative widths rather than fixed inches. Set margins to default and scaling to 100%, and all 20 problems fit.
When these become easy, move along the related links below rather than adding more problems to the same sheet.
