How the Unit Converter works

One meter is 39.37007874 inches. Both units are defined against the same SI base unit, so the factor is derived from two exact definitions rather than measured. It is exact in principle and does not land on a round number.

Worked through: 1.8 m x 39.3700787 = 70.8661 in.

Going the other way, one inch is 0.0254 meters.

For mental arithmetic: Multiply by 40 and take off 1.6%.

One meter is 39.3700787 inches, which is 1/0.0254 and therefore exact in principle while being unround in every digit. The conversion is mostly about objects a person handles: screen sizes, lumber and furniture. The one to keep is that a meter is about 39.4 inches, so it is a yard plus about three and a half inches. That is why a metric and an imperial tape measure drift visibly apart over a couple of meters and why mixing them on a build is a bad idea.

Precision is worth matching to the input. A measurement given as 0.5 m carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
