How It Works
Length converters work by expressing every unit relative to a single base unit — here, the metre (the SI base unit of length). Each unit has an exact conversion factor: 1 inch = 2.54 cm, 1 foot = 0.3048 m, 1 yard = 0.9144 m, 1 mile = 1609.344 m, and 1 nautical mile = 1852 m. To convert, the value is first multiplied by its from-unit factor to get metres, then divided by the to-unit factor. Because the metric system is decimal (each step is a power of ten — mm, cm, m, km), metric-to-metric conversions just shift the decimal point. Imperial units (inch, foot, yard, mile) descend from historical body-based measures and use irregular multipliers (12 inches to a foot, 3 feet to a yard, 1760 yards to a mile), which is why a converter is handy. India officially uses the metric system, but feet and inches remain common for height and real estate.
Formula
Result = value × (metres per from-unit) ÷ (metres per to-unit). Base unit: metre. Exact: 1 in = 2.54 cm, 1 ft = 0.3048 m, 1 mi = 1609.344 m.
Frequently Asked Questions
How many centimetres are in an inch?
Exactly 2.54 centimetres. This is a defined (exact) conversion, so 1 inch = 2.54 cm, 12 inches (1 foot) = 30.48 cm, and 1 metre ≈ 39.37 inches.
How do I convert feet to metres?
Multiply feet by 0.3048. For example, 6 feet = 6 × 0.3048 = 1.8288 metres. To go the other way, divide metres by 0.3048.
How many metres are in a kilometre?
1 kilometre = 1,000 metres. The metric system is decimal, so each prefix step is a power of ten: 1 km = 1,000 m, 1 m = 100 cm, 1 cm = 10 mm.
What is a nautical mile and how is it different from a mile?
A nautical mile (1,852 m) is used in aviation and maritime navigation and is based on one minute of latitude. A statute (land) mile is 1,609.344 m, so a nautical mile is about 15% longer.
How do I convert a height like 5'7" to centimetres?
Convert each part to cm and add: 5 ft = 152.4 cm, 7 in = 17.78 cm, total = 170.18 cm. In the converter, enter feet and inches separately or convert the total inches (67 in = 170.18 cm).
