Feet conversion reference
Feet to Millimeters
One feet is 304.8 millimeters, and one millimeters is 0.003281 feet.
A millimeter is one thousandth of a meter. It is the unit for precision work — engineering tolerances, rainfall, wire gauges and the thickness of paper or sheet metal.
- 1 ft= 304.8 mm
- 5 ft= 1,524 mm
- 10 ft= 3,048 mm
Feet to Centimeters
One feet is 30.48 centimeters, and one centimeters is 0.032808 feet.
A centimeter is one hundredth of a meter. It is the everyday metric unit for short distances: body measurements, clothing sizes, furniture and school rulers.
- 1 ft= 30.48 cm
- 5 ft= 152.4 cm
- 10 ft= 304.8 cm
The centimeter is exactly one hundredth of a meter, written 0.01 m, and it is the unit most metric rulers and tape measures are marked in, with ten millimeters to one centimeter.
It appears on clothing labels, school rulers, rainfall reports and body measurements, and in medicine for wound sizes. A person's height is commonly recorded in centimeters on metric forms.
Feet to Meters
One feet is 0.3048 meters, and one meters is 3.28084 feet.
The meter is the SI base unit of length, defined as the distance light travels in a vacuum in 1/299,792,458 of a second. It is used for room sizes, heights, fabric and track distances.
- 1 ft= 0.3048 m
- 5 ft= 1.524 m
- 10 ft= 3.048 m
The meter is the base unit of length in the International System, defined by the distance light travels in a vacuum in 1/299,792,458 of a second.
It measures room dimensions, fabric sold by the metre, athletic tracks, water depth and building heights. Scientific work uses meters and its decimal multiples, from nanometers to gigameters, almost everywhere outside everyday imperial trade.
Feet to Kilometers
One feet is 3.048e-4 kilometers, and one kilometers is 3,280.839895 feet.
A kilometer is 1,000 meters. It is the standard unit for road distances and speed limits, and the one used on road signs and by police across Tanzania and most of the world.
- 1 ft= 3.048e-4 km
- 5 ft= 0.001524 km
- 10 ft= 0.003048 km
The kilometer is exactly 1,000 meters, the unit of length in the International System used for distances between places rather than across a room. It is written km and is the basis of the metric road network.
Road signs, speed limits, odometers and race distances use kilometers in most of the world. Maps quote distances in kilometers, and athletic events such as the marathon are described in kilometers.
Feet to Inches
One feet is 12 inches, and one inches is 0.083333 feet.
An inch is exactly 2.54 centimeters. It remains the standard unit for screen sizes, pipe and hose diameters, and tool sizes in imperial-measure countries.
- 1 ft= 12 in
- 5 ft= 60 in
- 10 ft= 120 in
An inch is exactly 2.54 centimeters, or 25.4 millimeters. Twelve inches make one foot and thirty-six make a yard, so the inch sits inside two larger imperial units.
Screen and tyre sizes are given in inches, as are pipe and hose diameters, wrench openings and the diagonal of a television. Rainfall is still recorded in inches in some countries.
Feet to Yards
One feet is 0.333333 yards, and one yards is 3 feet.
A yard is exactly 0.9144 meters, or 3 feet. It is the unit for fabric and carpet sales, and for sports distances such as the 22-yard cricket pitch.
- 1 ft= 0.333333 yd
- 5 ft= 1.666667 yd
- 10 ft= 3.333333 yd
The yard is exactly 0.9144 meters, three feet or thirty-six inches. It is a defined multiple of the meter, not an independent standard. Its value was fixed by the same international agreement that defined the foot and the inch.
Fabric, carpet and some flooring are still sold by the yard, and the chain and furlong used in land and horse racing are built from yards. American football is measured in yards.
Feet to Miles
One feet is 1.8939e-4 miles, and one miles is 5,280 feet.
A mile is exactly 1,609.344 meters, or about 1.609 kilometers. It is the standard road-distance unit in the United States and the United Kingdom.
- 1 ft= 1.8939e-4 mi
- 5 ft= 9.4697e-4 mi
- 10 ft= 0.001894 mi
The international mile is exactly 1,609.344 meters, or 1.609344 kilometers. It descends from the Roman mile of a thousand paces and remains the standard road distance in the United States and the United Kingdom.
Road signs and speed limits, distance markers on highways, running and cycling events and aviation track distances are quoted in miles in those countries. Nautical miles are separate and longer.
Feet to Nautical miles
One feet is 1.6458e-4 nautical miles, and one nautical miles is 6,076.115486 feet.
A nautical mile is exactly 1,852 meters — one minute of latitude. It is the standard unit for maritime and air navigation, which is why ship and aircraft speeds are given in knots per hour.
- 1 ft= 1.6458e-4 nmi
- 5 ft= 8.2289e-4 nmi
- 10 ft= 0.001646 nmi
What feet are used for
A foot is exactly 0.3048 meters, or 12 inches. It is used for height, altitude in aviation and room dimensions wherever imperial measurements are standard.
The foot is exactly 0.3048 meters, or twelve inches. United States survey work has used a separate survey foot, defined as 1200/3937 meters and equal to about 0.3048006 meters.
Aviation uses feet for altitude and flight levels worldwide, even in countries that measure road distance in kilometers. Building heights, room dimensions, timber and, in some places, body height are also quoted in feet.
The metric conversion is exact, since the foot is defined as 0.3048 meters, and the reverse is exact too. A displayed result is rounded to six decimal places at most, so a round trip can differ in the final digit.
The common slip is assuming a foot is close to a third of a meter when it is slightly longer, so rough mental division undershoots. Feet also belong to length, while square feet measure area and cubic feet measure volume.
The foot competes with the meter for height and building dimensions and with the inch for small spans. Because one meter is a little over three feet, treating a meter figure as feet overstates a dimension more than threefold.
Metric-to-metric conversions are exact. Imperial figures are exact by definition but are rounded for display, so a value converted back and forth can differ in the final digit.
Inside the metric units every length conversion is a shift of the decimal point, so millimeters to centimeters, meters to kilometers and the rest can be done by moving it. Which way, and how far, follows from the prefix alone.
Converting between metric and imperial is not a shift but a single exact multiplication, and the factor is the same one for that pair however large or small the value. The trap is mixing the two systems halfway, as when a distance is stated in meters and inches in the same sentence.
To check a length conversion, run it backwards, or convert through a familiar middle value such as a meter or a foot. The one thing to keep straight is pairs that differ by a thousand rather than by ten, since those are where a misplaced decimal point survives unnoticed.
