About Length Converter
Distances show up everywhere—from 3 mm circuit traces to 3 000 km road trips—and each context prefers its own unit. Tooloria’s Length Converter lets you switch between metres, kilometres, centimetres, millimetres, inches, feet, yards, statute miles and nautical miles with six adjustable decimal places. Surveyors can toggle “survey foot” for legacy plats, while runners can compare mile splits and kilometre paces side-by-side. All maths run locally in your browser, so draft blueprints or hiking routes never leave your device. Copy results with one click, swap units instantly and review your last five conversions in the on-page history—no account, no pop-ups, just standards-based factors derived from ISO 80000 and NIST tables.
Frequently Asked Questions
Which length units are included?
Metric: mm, cm, m, km. Imperial: in, ft (international & survey), yd, mi. Others: nautical mile, fathom, hand and point. The list expands as users request additional units.
How do you handle precision?
The converter keeps 12 significant digits internally and rounds to the decimal-place setting you choose (0–6). That covers everything from woodworking tolerances to rough walking estimates.
Will it work if I'm offline?
Yes. After the first visit, the tool is cached by your browser’s Service Worker. Return without internet and conversions still work; only optional ads and update checks are skipped.
