About Length Converter
Metric lengths are powers of ten of the metre (mm, cm, m, km). Imperial and US lengths are defined from the metre: 1 inch = 25.4 mm, 1 foot = 12 inches = 0.3048 m, 1 yard = 3 feet = 0.9144 m and 1 mile = 1760 yards = 1609.344 m.
Is it private?
Yes. Length Converter runs entirely in your web browser. What you type is never sent to Nolo or anyone else, and the page cannot send it anywhere: its security policy only allows it to talk to nolotools.com, which has no place to receive data. Nothing is stored either: close the page and it is gone. How Nolo works.
