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 by multiplying inches with factor 0.0833 from the table above
