Unit Conversion Methods
The following methods show how to convert SI units to
US units and vice versa.
1. To convert an SI unit to a US unit, multiply a SI unit
with the number in the following table.
Note) (SI Unit) X (Number) = (US Unit)
Note) 1mm X 0.03937 = 0.03937 in
2. To convert a US unit to an SI unit, divide the US unit
by the number in the following table.
Note) (US Unit) ÷ (Number) = (SI Unit)
Note) 1 in ÷ 0.03937 = 25.4 mm
