Convert length and distance units including meters, centimeters, millimeters, kilometers, inches, feet, yards, miles, nautical miles, micrometers, nanometers, and more.
Meters to feet:
1 m = 3.28084 ft
Feet to meters:
1 ft = 0.3048 m
Inches to millimeters:
1 in = 25.4 mm
Miles to kilometers:
1 mi = 1.60934 km
Length conversions are useful for building dimensions, material cut lists, engineering drawings, pipe lengths, wire lengths, machining tolerances, land measurements, road distances, and metric-to-imperial comparisons.
Use this converter when comparing metric, U.S. customary, imperial, engineering, surveying, and scientific length units.
Your result shows the entered length converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering and construction work, make sure the length unit matches your drawing, material list, field measurement, equipment specification, or calculation sheet.
Length is the measurement of distance between two points.
The SI base unit of length is the meter, abbreviated as m.
One meter equals approximately 3.28084 feet.
One inch equals exactly 25.4 millimeters.
This converter is designed for length magnitude conversions, so it uses non-negative values.
