Unit conversions
Length converter
Explain this equation
Converts a length from one unit to another, such as metres, millimetres, feet or inches. Use it when drawings, products or data sheets mix units.
Value is the length you enter. Result is the same length in the unit you pick.
The equation is result = value because the physical length does not change; only the unit describing it does. Internally the value is converted to metres and then to the chosen unit.
Sense check: 1 inch is 25.4 mm. 1 foot is 304.8 mm. 1 m is about 3.28 ft.
Watch out: pipe nominal sizes in inches are not the same as actual dimensions.
Enter your values to see the result.
Good to know
Choose another compatible output unit beside the answer. UK and US gallons are separate; Btu uses the International Table definition.
