Nautical Measurement

Both distance and speed are measured differently on the water then what they are on land. Most everyone has heard the terms "nautical mile" and "knots". To assist you in converting the nautical measurements to the ones we more accustomed to, we have put together a little information that will help.

Statute Mile to Nautical Mile
1 statute mile is equal to .868976 nautical mile
Example: 25 miles x .868976 = 21 . 72 nautical miles
Nautical Mile to Statute Mile
1 nautical mile is equal to 1.15078 statute mile
Example: 25 nautical miles x 1.15078 = 28.77 statute miles
Miles per hour to knots
1 mile per hour is equal to .868976 knots
Example: 15mph x .868976 = 13 . 034 knots
Knots to miles per hour
1 knot is equal to 1.15078 miles per hour
Example: 20 knots x 1.15078 = 30 . 156 mph
Fahrenheit to Celsius
To convert degrees Fahrenheit to degrees Celsius subtract 32 then divide by 1.8
Example:  75°F - 32  ∕ 1.8= 23.88°C
