How it works
Every length conversion routes through one reference — this converter uses the metre — so any pair of units can be linked without memorising a table. Convert the input to metres, then out to the target. The key factors are worth knowing by heart: 1 inch = 2.54 cm exactly, 1 foot = 30.48 cm, 1 yard = 0.9144 m, 1 mile = 1.609 km. In the other direction, 1 m ≈ 3.281 ft and 1 km ≈ 0.621 mile. Notice that these are exact, not rounded. Since 1959, the inch has been *defined* as precisely 2.54 centimetres by international agreement, which quietly made the imperial system a derivative of the metric one. Every foot, yard and mile in use today is ultimately expressed in terms of the metre.

Frequently asked questions
How many centimeters are in an inch?
Exactly 2.54 cm = 1 inch.
How do I convert meters to feet?
Multiply by 3.281 — 1 meter = 3.281 feet.
Why is an inch exactly 2.54 cm?
Because it was defined that way. In 1959 the main English-speaking countries agreed on the "international inch" of exactly 2.54 cm, replacing several slightly different national inches — so the value is a definition, not a measurement.
