Q&A for How to Convert Kilometers to Miles

Only in the United Kingdom and United States. The rest of the world uses kilometers.

(108 km)(0.621371 mi/km) = 67.108 miles.

Many centuries ago the Roman Empire introduced the mile into the UK, and they've simply stuck with it. From its beginning, the US adopted the British mile.

1 kilometer=1,000 meters.

You want to know how many groups of 8 km there are in a distance of 72 km. So you divide 8 into 72. That's 9. So there are 9 groups of 8 km in 72 km, and each group consists of 5 miles. 9 x 5 = 45 miles.

Multiply kilometers by 3,280.84.

Multiply miles by 5,280.

One mile equals 1.609 kilometers. Multiply 60 by 1.609. That's 96.56 kilometers.

Divide 15 by 2 6/7: 15 ÷ 2 6/7 = 15 ÷ 20/7 = (15)(7/20) = 105/20 = 5¼ kilometers.

There are 1.61 kilometers in a mile. So 12 miles equal (12)(1.61) = 19.32 kilometers.

Five point seven five eight kilometers (or five and seven-hundred fifty-eight one-thousandths kilometers).

Americans might use yards in certain applications but more often use miles in decimal or fractional form.

It doesn't matter whether the distance is long. Use the conversion method shown above.

1 square km = 1km x 1km = 0.621371 mi x 0.621371 mi, which is 0.386102 square mile. Multiply your square km by 0.386102. For example, 64 square km x 0.386102 = 24.71 square miles.

1 inch = 0.0254 meter. 1 foot = 12 inches, so 1 foot = 12 x 0.0254 = 0.3048 meter. One way to remove decimals is to move the decimal point (10,000 ft = 3048 m) and then divide by a common factor to get 1250ft = 381m. This is not an especially useful conversion factor, so you really should learn to use the equation with decimals.

The answer is close but not exact. 1 km = 0.621 371 2 mi, 8 km = 8 x 0.621 371 2 mi = 4.970 969 6 mi. This is rounded to 5 mi, so there is a small error of about 0.58%. This is good for quickly estimating distance but not when accurate measurements are needed.
