Spike's Calculators

Calculate the time it takes to travel a certain distance in 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/Miles

- enter the distance in miles
- the speed in knots

- the distance in miles converted to nautical miles
- the distance in miles converted to kilometres
- 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 mile (mi) = 1.609344 kilometres (km) one mile (mi) = 0.868976241900649 nautical miles (nmi) 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 1222 miles at a speed of 152 knots?

First, convert the miles to nautical miles;

1222 * 0.868976241900649 = 1061.8889676

1222 miles equal 1061.889 nautical miles

Divide the distance of 1061.889 nautical miles by the speed of 152 knots to get the time in hours;

1061.889 ÷ 152 = 6.9861

It will take 6.9861 hours to travel the 1222 miles at a speed of 45 knots. 6 hr - 59 min - 10 sec
