The Distance Calculator converts length and distance units such as miles, kilometres, metres, feet, yards, and inches. Enter a length in one unit and read the others with the factor and working shown. The page is a unit converter for a distance already known, not a tool that finds distance between two map coordinates.
Coordinate-to-coordinate distance (great-circle or planar formulas) belongs on the geometry Distance Calculator. This Distance Calculator only changes the unit label on a length value using audited factors such as 1.609344 kilometres per international mile.
Convert a distance between units
The Distance Calculator routes every length through metres (SI), then formats the selected target unit. Road travel often uses miles or kilometres. Construction and height work often use feet and inches. Science and international specs use metres and kilometres.
Choose source and target units, enter the number, and results update live. Cascade mode lists many length units at once so a survey measurement in metres can be compared with a deed description in feet without retyping.
Bidirectional fields mean typing into either side keeps the metre base consistent. Exact factors such as 0.3048 metres per international foot produce exact reverse conversions within display rounding.
Convert miles to kilometres
One international mile equals exactly 1.609344 kilometres. Miles convert to kilometres by multiplying by 1.609344. Kilometres convert to miles by dividing by 1.609344.
km = miles × 1.609344
miles = km ÷ 1.609344Worked example: convert 26.2 miles to kilometres (marathon distance orientation).
1. Multiply by 1.609344. 26.2 × 1.609344 ≈ 42.1648 km.
2. Reverse check. 42.1648 ÷ 1.609344 ≈ 26.2 miles.
A simpler case: 10 miles × 1.609344 = 16.09344 km. The Distance Calculator shows that multiply step under the result. Nautical miles are a different unit (1852 metres); use the knot/nautical options only when the source explicitly says nautical, not statute miles.
Convert metres to feet
One metre equals 100/30.48 feet, or approximately 3.280839895 feet, because one international foot is exactly 0.3048 metres. Metres convert to feet by dividing by 0.3048 (or multiplying by 3.280839895). Feet convert to metres by multiplying by 0.3048.
feet = metres ÷ 0.3048
metres = feet × 0.3048Worked example: convert 100 metres to feet.
1. Divide by 0.3048. 100 ÷ 0.3048 ≈ 328.084 feet.
2. Reverse check. 328.084 × 0.3048 ≈ 100 metres.
Five metres ≈ 16.404 feet. The Distance Calculator uses the exact 0.3048 definition so metre-foot pairs match international length standards rather than older US survey foot variants, unless a specialized survey unit is explicitly selected in the table.

Cascade view shows the same length across miles, kilometres, metres, feet, yards, and inches from one entry. One kilometre appears as 1000 metres, about 0.621371 miles, and about 3280.84 feet in the same panel.
| Input | metres | feet | miles | km |
|---|---|---|---|---|
| 1 m | 1 | 3.28084 | 0.000621 | 0.001 |
| 1 mile | 1609.344 | 5280 | 1 | 1.609344 |
| 1 km | 1000 | 3280.84 | 0.621371 | 1 |
| 100 ft | 30.48 | 100 | 0.018939 | 0.03048 |
Clicking a cascade row can preload that unit into the main pair converter when the product supports it. Nearby-value tables centred on the entered number help estimate without typing every neighbouring distance.
Yards and inches follow the same international foot: 1 yard = 3 feet = 0.9144 metres exactly, and 1 inch = 0.0254 metres exactly. A fencing run of 50 yards is 45.72 metres; a clearance of 6 inches is 0.1524 metres. The Distance Calculator applies those identities when yard or inch is selected, so mixed imperial drawings can be rewritten in metres without changing the physical length.
Road signs that show both miles and kilometres already use 1.609344. Recreating that pair by hand for a trip plan of 120 miles gives 120 × 1.609344 = 193.12128 km. Using 1.6 as a mental shortcut understates the distance by a little over one kilometre on that trip, which is why the audited factor stays on the working line.
FAQ
How do I convert miles to kilometres?
To convert miles to kilometres, multiply miles by 1.609344. For example, 10 × 1.609344 = 16.09344 km. The Distance Calculator multiplies by that international-mile factor.
How do I convert metres to feet?
To convert metres to feet, divide metres by 0.3048. For example, 100 ÷ 0.3048 ≈ 328.084 ft. The Distance Calculator uses the international foot definition of 0.3048 m.
How many kilometres are in one mile?
One international mile equals 1.609344 kilometres exactly. The Distance Calculator multiplies miles by that factor for every mile-to-kilometre conversion.
Is this the map distance between two points?
No. This Distance Calculator converts length units. Distance between two latitude/longitude points belongs on the geometry Distance Calculator, which applies a coordinate formula.
How many feet are in a metre?
One metre equals about 3.280839895 feet. The Distance Calculator returns that figure when converting metres to feet with the 0.3048 m foot definition.
How do I convert kilometres to miles?
To convert kilometres to miles, divide kilometres by 1.609344. For example, 100 ÷ 1.609344 ≈ 62.137 miles. The Distance Calculator divides by the same factor used for the reverse pair.
Can I convert inches and yards?
Yes, when those units appear in the length list. The Distance Calculator scales them through metres using audited factors (for example, 1 yard = 0.9144 m exactly under the international definitions tied to 0.3048 m per foot).
What mile definition is used?
The international mile of exactly 1609.344 metres (1.609344 km). The Distance Calculator does not treat a nautical mile as a statute mile.
Summary
The Distance Calculator converts length and distance units through SI metres, including 1.609344 km per international mile and 0.3048 m per international foot (about 3.28084 feet per metre). Cascade views show many units from one entry.
The page does not compute distance between coordinates; it only converts a known length from one unit to another with factors and working shown.
