About this calculator

The span is a historical, body-based unit of length equal to the distance from the tip of the thumb to the tip of the little finger on a spread hand — standardized at 9 inches, or 22.86 centimeters. It's an old but still occasionally referenced unit in carpentry, textiles, and historical or biblical measurements.

This converter multiplies (or divides) by 22.86 to switch between spans and centimeters in either direction. It's useful for anyone reading historical texts, traditional craft instructions, or older measurement references that use spans, and who needs a modern metric equivalent to work with.
