Convert feet (ft) to mm, cm, m, km, inches, yards, miles, and nautical miles instantly. A free length converter for construction, engineering, and home use.
About This Calculator
The Feet Converter is a free online tool that instantly converts any length in feet to all major metric and imperial units. Whether you are a construction professional measuring room dimensions, a student working on a science project, a runner tracking distances, or an aviation enthusiast converting altitudes, this calculator provides accurate conversions to millimeters (mm), centimeters (cm), meters (m), kilometers (km), inches (in), yards (yd), miles (mi), and nautical miles (nmi).
The conversion uses the internationally accepted standard where 1 foot equals exactly 0.3048 meters. From this base conversion, all other unit values are derived: 1 foot = 30.48 centimeters, 1 foot = 12 inches, 1 foot = 1/3 yard, and 1 mile = 5,280 feet. The calculator also supports scientific and specialized conversions like feet to nautical miles (1 nmi = 6,076.12 ft) used in aviation and maritime contexts. A comparison chart visualizes the relative magnitude of each converted unit, making it easy to compare lengths at a glance.
Regional Notes
United States: The foot is the primary unit for height, construction dimensions, real estate (square footage), and road distances alongside miles. US customary units remain dominant in everyday life, construction, and engineering.
United Kingdom: While the UK officially uses the metric system, feet remain common for measuring human height, room dimensions, and in construction. Road signs show distances in miles and yards. The UK foot is identical to the US foot (international foot of 0.3048 m).
India: India uses the metric system officially, but feet are widely used in real estate, construction, and property measurement. Land area is often quoted in square feet, building heights in feet, and human height in feet and inches.
Canada, Australia, New Zealand: These metric-system countries still use feet informally for human height, sports fields, and some construction applications.
Frequently Asked Questions
How do I convert feet to meters?
To convert feet to meters, multiply the number of feet by 0.3048. For example, 10 feet × 0.3048 = 3.048 meters. Our calculator does this instantly for you.
How many inches are in a foot?
There are exactly 12 inches in one foot. To convert feet to inches, multiply the feet value by 12. For example, 5 feet × 12 = 60 inches.
How do I convert feet to centimeters?
Multiply the feet value by 30.48 to get centimeters. For instance, 6 feet × 30.48 = 182.88 centimeters. This is useful for height conversions and metric system measurements.
How many feet are in a mile?
There are 5,280 feet in one mile. To convert miles to feet, multiply the miles by 5,280. To convert feet to miles, divide the feet by 5,280.
What is the difference between a foot and a yard?
One yard equals 3 feet. Yards are commonly used for measuring fabric, sports fields (American football), and moderate distances, while feet are used for height, room dimensions, and construction measurements.
Is this feet converter free to use?
Yes, this feet converter is completely free to use with no limits, registration, or hidden fees. Convert feet to any unit as many times as you need.
How do I convert feet to kilometers?
Divide the feet value by 3,280.84 to get kilometers. For example, 10,000 feet ÷ 3,280.84 = 3.048 kilometers. This is useful for aviation altitudes and long-distance measurements.
Can I convert feet to nautical miles?
Yes, divide feet by 6,076.12 to get nautical miles. Nautical miles are used in aviation and maritime navigation, where one nautical mile equals approximately 6,076 feet.
