800 knots = 920.623558 miles
The answer will depend if you mean 800 nautical miles (as would often be used in relation to knots) or 800 normal miles. If 800nm (nautical miles) then the answer is simply 800/5 = 160 hours. If normal miles then we can answer by making a conversion from knots to mph first. 5 knots = 5 * 1.15077945 = 5.75389725 mph Thus time = 800/5.75389725 = 139.036 hours (accurate to 3 decimal places).
1 knots = 1.15077945 miles 23 knots = 26.46792735 miles
The units are the same. So there are 800 miles in 800 miles.
90 knots = 103.57015 mph
To convert knots to miles per hour, you can multiply the speed in knots by 1.15078. Therefore, 70 knots is approximately 80.6 miles per hour.
41 Knots is 47.19 miles per hour.
439 knots=505.192178 miles per hour
40 knots=46.0311779 miles per hour
36 knots=41.4280601 miles per hour
1 mph = 0.87 knots
287.631 knots.
