How it works

This calculator lets you convert between millimeters, inches, AWG, BWG, SWG and fractional inches.

If the value cannot be converted to an exact number (like when converting to fractional inches), it will give you both the closest larger match and the closest smaller match, plus the errors in percents. The closest match will be marked in green.
