To convert meters to feet, multiply the meter value by 3.28084. For example, 1 meter equals approximately 3.2808 feet. You can also use this tool by selecting 'Meter (m)' as the From unit and 'Foot (ft)' as the To unit.
Metric units are based on powers of 10. To go from meters to centimeters, multiply by 100; to kilometers, divide by 1000; to millimeters, multiply by 1000. This converter handles all those conversions automatically.
One inch equals exactly 2.54 centimeters. So to convert inches to cm, multiply your inch value by 2.54. For example, 12 inches = 30.48 cm.
There are exactly 5,280 feet in one mile. This is a fixed definition in the imperial measurement system. In metric terms, 1 mile equals approximately 1.60934 kilometers.
The metric system uses meters as the base unit, with prefixes like milli-, centi-, and kilo- to scale up or down by powers of 10. The imperial (US customary) system uses inches, feet, yards, and miles, which have less uniform relationships between units.
One yard equals 3 feet, and 1 foot equals 30.48 centimeters, so 1 yard = 91.44 centimeters. To convert any yard value to centimeters, multiply by 91.44.
To convert kilometers to miles, multiply by 0.621371. For example, 10 km × 0.621371 = 6.21371 miles. Conversely, to convert miles to kilometers, multiply by 1.60934.
This converter supports millimeters as the smallest unit. One millimeter equals 0.001 meters, 0.1 centimeters, or approximately 0.03937 inches. For even smaller units like micrometers or nanometers, a specialized scientific converter would be needed.
