Length Converter
Convert metres, feet, inches, miles, and kilometres.
Length and distance, converted
Length is the everyday conversion — metric to imperial and back. One inch is exactly 2.54 cm and one mile is 1,609.34 m, the fixed factors this uses so results stay consistent.
From a DIY project mixing a metric tape measure with an imperial plan, to reading a running distance in miles versus kilometres, it removes the mental arithmetic that leads to costly mistakes.

Frequently Asked Questions
How does the length converter work?
The calculator converts the input to meters first, then divides by the target unit factor. For example, 12 feet becomes 3.6576 meters because one foot is exactly 0.3048 meters.
When should I use this converter?
Use it when specs mix metric and imperial lengths, such as product dimensions, room measurements, shipping boxes, or design handoff notes.
What is the main limitation?
Round only at the display step; keep a few decimals when converting construction or manufacturing measurements.
Is this converter private?
Yes. The conversion runs entirely in your browser, so your values are not uploaded, stored, or sent to a server.
