This length converter works by converting your input value to meters first (using standard exact conversion factors), then converting from meters into your target unit. For example, converting inches to centimeters uses the exact factor 1 inch = 2.54 cm internally, so 10 inches converts to 25.4 cm.
Frequently used conversions include feet to meters (1 foot = 0.3048 m), miles to kilometers (1 mile = 1.609344 km), and centimeters to inches (1 cm ≈ 0.3937 in). The quick reference table below shows several common length and distance conversions at a glance.
Converting 10 inches to centimeters gives exactly 25.4 cm (10 × 2.54), and converting a 26.2-mile marathon distance to kilometers gives approximately 42.16 km (26.2 × 1.609344), the standard marathon distance you'll often see quoted in kilometers.
Confusing a UK/international mile with a nautical mile, a nautical mile (1,852 m) is longer than a standard statute mile (1,609.344 m), mixing them up matters most in aviation and maritime contexts.
Rounding intermediate results before a multi-step conversion, converting inches to feet to meters and rounding at each step can introduce small compounding errors, convert directly in one step whenever possible.
Assuming 'meter' and 'yard' are close enough to treat as equal, a yard (0.9144 m) is about 8.6% shorter than a meter, a gap that adds up over longer distances like a football field or running track.
Conversions use standard international conversion factors and are accurate to six decimal places.
Yes, you can convert between any combination of metric (mm, cm, m, km) and imperial (in, ft, yd, mi) units.
