Length Converter
Metres, feet, miles, inches & more.
Quick conversions
All units
Batch convert (one value per line)
Converts every line from the “From” unit to the “To” unit. Blank or non-numeric lines are skipped.
This free length converter converts between metric, imperial, nautical, scientific and astronomical units of length — from ångströms and microns through metres, feet, miles and nautical miles up to astronomical units, light years and parsecs.
Beyond a simple from/to conversion it shows the value in every unit at once, a plain-language formula, and a feet-and-inches compound readout for heights. You control the output precision (auto significant figures or a fixed number of decimals) and optional thousands separators, tap quick-conversion presets like cm→in or m→ft, and use batch mode to convert a whole column of values at once. Copy any single result or the entire table with one click.
