Last week I posted the Imperial version of a new tool I’ve updated recently. I promised I’d post the Metric version of the tool this week so here it is. You’ll find the Imperial version here if you missed the post.

If you stack them one over the other, you get a quick scale conversion calculator across 12 Imperial and metric scales. No batteries required.

Download the tool with the buttons below.

Here is the tool layout for A4 format paper.
