One meter
1 meter equals 100 centimeters, about 3.28084 feet, and about 39.37008 inches.
Convert length and distance between millimeters, centimeters, meters, kilometers, inches, feet, yards, and miles using exact shared conversion factors.
Every conversion first converts the source value to meters, then converts meters to the target unit. This base-unit design avoids inconsistent pairwise formulas.
Metric units scale by powers of ten. US customary relationships include 12 inches per foot, 3 feet per yard, and 1,760 yards per mile.
target = value × meters-per-source ÷ meters-per-target1 inch = 0.0254 meter = 2.54 centimeters1 mile = 1609.344 meters = 1.609344 kilometers1 meter equals 100 centimeters, about 3.28084 feet, and about 39.37008 inches.
5 kilometers is approximately 3.1068559612 miles.
12 inches equals exactly 1 foot and 30.48 centimeters.
1 mile equals exactly 1.609344 kilometers, 1,760 yards, and 5,280 feet.
Millimeters, centimeters, meters, and kilometers use decimal scaling.
Inches, feet, yards, and miles use exact standardized relationships.
The converter accepts negative numbers mathematically even though physical lengths are commonly non-negative.
The shared unit engine defines an inch as exactly 0.0254 meter, a foot as 0.3048 meter, a yard as 0.9144 meter, and a mile as 1609.344 meters.
Multiply by the source unit's meter factor and divide by the target unit's meter factor.
Exactly 2.54 centimeters.
Exactly 5,280 feet.
Exactly 1.609344 kilometers.
Calculations retain floating-point precision; rounding occurs only for display.
Yes. Negative values are mathematically valid inputs.
