A nautical mile is now 1852 m (6080 feet) - it was originally defined as one minute of arc of a great circle - or 1/60 of 1/360 of the earth's circumference. The ordinary mile is more precisely known as the statute mile - as defined by statute or law.

Example - Inches to Feet

4" (inches) can be converted to feet as

4 (inches) / 12 (inches/foot) = 0.33333 feet
