2.54 cm per inch, exactly

The inch has been internationally defined as exactly 2.54 centimeters since 1959, so this conversion carries no rounding error in either direction.

Where metric shows up in lumber work

Centimeters come up most often with imported furniture plans, European workshop tools and jigs, and some imported hardwood stock sold by metric dimension. This converter handles length both directions so you can translate a metric plan or spec sheet into the inches most US lumber is sold in.

The cm-to-inch relationship is an exact, internationally defined conversion (1 inch = 2.54 cm exactly), not an approximation.
