Unit Conversion Methods
This is a method for converting between SI and US units.
1. Multiply the SI unit by the numbers in the table below to
obtain the US unit.
Note) (SI unit) X (number) = (US unit)
Note) 1 mm X 0.03937 = 0.03937 in
2. Divide the US unit by the numbers in the table below to
obtain the SI unit.
Note) (US unit) ÷ (number) = (SI unit)
Note) 1 in ÷ 0.03937 = 25.4 mm
