Length conversion multiplies by an exact factor into meters, then out to the unit you picked. One inch is 25.4 mm, one foot is 0.3048 m, one statute mile is 1609.344 m, and one nautical mile is 1852 m.
Area from two sides is the acreage calculator. This page only changes the unit of a length you already have.
Metric steps versus feet and inches
A kilometer is 1000 m, a centimeter is 0.01 m, and a millimeter is 0.001 m. The foot cluster is not a power of ten: 1 foot = 12 inches and 1 yard = 3 feet. One meter is 3.28084 feet on this page.
A nautical mile is not a statute mile
The statute mile is 1609.344 m. The nautical mile is 1852 m, so the two are not interchangeable. The six-digit display of one statute mile is 1609.34 m.
Worked example: 1 meter
Set from meters and to feet with value 1. The result is 3.28084 ft. The same meter is 39.3701 inches.
\[ 1\,\mathrm{m}=3.28084\,\mathrm{ft} \]

What does the mile field use?
The statute mile, 1609.344 m. A nautical mile is a separate choice at 1852 m.
Why does 1 mile not show 1609.344?

Can this page turn a room into acres?
No. It converts one length. Use acreage when you have a width and a length.

Assumptions and limitations
Results show at most six significant digits. The page does not split a length into feet plus leftover inches.
