Frequently Asked Questions
How do I convert fractions to millimeters?
You divide the top number of the fraction by the bottom number, and then multiply by 25.4. Our tool does this automatically using standard construction tape measure intervals (1/16ths, 1/8ths, etc).
Is exactly 1 inch equal to 25.4 mm?
Yes, since the 1959 International Yard and Pound Agreement, one inch is legally and scientifically defined as exactly 25.4 millimeters. There is no discrepancy or rounding at the fundamental level.
Why do US plans use fractions instead of decimals?
Because it is easier to divide a piece of wood in half repeatedly (1/2, 1/4, 1/8, 1/16). It is an artifact of manual craftsmanship, whereas the metric system is purely base-10.
