Spike's Calculators

Calculate the time it takes to travel a certain distance in nautical miles based on a speed in knots. A knot is a unit of speed equal to one nautical mile per hour. The symbol used for a knot is kn or kt.

Knots/Nautical Miles

- enter the distance in nautical miles
- the speed in knots

- the distance in nautical miles converted to kilometres
- the distance in nautical miles converted to miles
- knots converted to metres per second
- knots converted to feet per second
- the time in seconds
- the time in minutes
- the time in decimal hours
- the time in an hour, minute, and second format

time = distance ÷ speed

one nautical mile (nmi) = 1.852 kilometres (km) one nautical mile (nmi) = 1.15077944802354 miles (mi) one knot = 1 nautical mile (nmi) per hour one knot (kn) = 0.514444444444444 metres per second (m/sec) one knot (kn) = 1.68780985710119 feet per second (ft/sec)

How long will it take to travel 4325 nautical miles at a speed of 45 knots?

Calculate the time in hours by dividing the nautical miles by the knots;

4325 ÷ 45 = 96.1

It will take 96.1 hours to travel the 4325 nautical miles at a speed of 45 knots. 96 hr - 6 min - 40 sec
