Measurement conversion worksheets

Every conversion here is exact and every one of them is a power of ten, which is the argument for the metric system in one page of arithmetic: converting is moving the point, and the only thing to get right is which way. Nothing on this sheet converts between the two systems — meters into feet is an approximation, and it is a different lesson.

The three quantities are mixed rather than blocked, deliberately. A page of nothing but length lets a child work out the multiplier once and apply it fourteen times; a mixed page asks the actual question every time, which is what a test does.

The answers were worked out when the problems were, so the key is the same page with the answers drawn in rather than a second attempt at the same questions — there is no way for the two to disagree. The number in the footer is the seed the sheet was built from: it is printed so that the identical sheet can be had again next week, rather than one that merely looks like it.

This page is one sheet out of a family that can print thousands, and the settings behind it — how many problems, how big the numbers get, how they are laid out, whether there is room to work — are all switches. The builder link at the top of the page carries this sheet’s own settings, so the bench opens on exactly the sheet here rather than on a blank one.

The configuration travels in the address bar rather than on a server, so the link can be bookmarked or sent to somebody as it stands — and what they open is this sheet, down to the seed, rather than another one like it.

Not in the games. The times tables that turn 3.5 kg into grams are, in The Grid.
