Switching between metric and imperial length units trips up almost everyone at some point. This converter handles metres, centimetres, kilometres, inches, feet, yards and miles and gives the answer instantly.
Everything is converted through a common base: 1 inch is exactly 2.54 cm, 1 foot is 0.3048 m and 1 mile is about 1.609 km. So 10 km is roughly 6.21 miles, and 6 feet is about 1.83 m.
It is handy for travel, DIY projects, following international recipes or instructions, and any time a measurement is quoted in units you do not think in.
Exactly 2.54 cm. So 12 inches (one foot) is 30.48 cm, and a metre is about 39.37 inches.
Multiply kilometres by 0.6214, or divide by 1.609. A 10 km run is about 6.2 miles.
Decimals are normal when a conversion does not produce a whole number.
