Convert mm to feet

Milímetro

Overview
A millimeter (mm) is an SI unit of length representing one-thousandth of a meter. Thanks to the modern definition of the meter—based on the distance light travels in 1⁄299 792 458 of a second—a millimeter is equally precise, even though early meters were once defined by metal bars.

Historical Context
El prefijo mili- (Latín mille meaning “thousand”) denotes 10⁻³. While the meter has evolved—from a physical prototype to a light-based constant—the ratio (1 mm = 0.001 m) has never changed.

Where It’s Used
Millimeters are essential for fine measurements: engineering tolerances, technical drawings, and any situation demanding sub-centimeter accuracy. On our site, you can instantly convert millimeters into larger units with a click.

Overview
A foot (ft) is a traditional unit in the Imperial and U.S. customary systems. Since 1959, it’s defined as exactly 0.3048 meters—three feet make a yard, and each foot contains 12 inches.

Historical Context
Across ancient cultures, the “foot” fluctuated between roughly 250 mm and 335 mm, often based on human anatomy. An international accord in 1959 settled on 0.3048 m to synchronize global measurements.

Where It’s Used
Feet remain the norm in the U.S., Canada, and U.K. for building plans, personal height, and sports field dimensions. Use our converter to switch between metric and customary units in seconds.
