Length Converter
Also known as Distance Converter. These names use this same conversion workflow.
Compare a measurement in the units used by your drawing, tape measure or supplier. Choose a direction and enter the measured length; the result changes units, not the physical length. International customary measures are used; survey and mixed feet/inches measurements need a different workflow.
Scope and assumptions
SI metric units and international inch=0.0254m, foot=0.3048m, yard=0.9144m, mile=1609.344m. Scalar lengths only: no survey-foot, nautical-mile, mixed feet/inches, astronomical distance or geometric measurement claim.
Only the directions listed below are supported. Switching units retains your entered amount and validates it against the new direction.
Meters = feet × 0.3048.
