Most US tape measures are graduated to 1/16". Cabinetry and millwork sometimes go to 1/32"; precision machining uses thousandths. The fraction is reduced to lowest terms (so 8/16" shows as 1/2"). For metric, use the millimeter value shown.

About

Enter a decimal inch measurement. Get the closest fraction at the precision you pick (1/2 down to 1/64). Includes millimeter equivalent. Use this when CAD spits out 2.375 and you need to read it on a tape measure.

How to use

  1. Enter decimal inches.
  2. Pick the precision (most US tapes go to 1/16).
  3. Read the rounded fraction.

FAQ

Why are some answers shown reduced?+

8/16 reduces to 1/2. The tool always shows the simplest form, which is what you'd actually read on a tape measure.
