How to Convert Miles per Hour per Second to Knots per Second
The mile per hour per second and knot per second are both units of acceleration. 1 knot per second equals 1.1507784538 miles per hour per second. This means to convert miles per hour per second to knots per second, you divide by 1.1507784538.
Formula
Step-by-Step Example
Convert 5 mph/s to knots per second:
We need to convert miles per hour per second to knots per second
Since 1 kn/s = 1.1507784538 mph/s, divide by 1.1507784538
5 ÷ 1.1507784538 = 4.3448849632
5 mph/s = 4.3448849632 kn/s

About These Units
Mile per Hour per Second (mph/s)
Miles per hour per second (mph/s) is commonly used for vehicle acceleration. A car going 0-60 mph in 6 seconds accelerates at 10 mph/s (4.47 m/s² or 0.46g). Sports cars achieve 15-20 mph/s. One mph/s equals 1.467 ft/s².
Knot per Second (kn/s)
Knots per second (kn/s) measures acceleration in aviation and maritime applications. One knot per second equals 0.514 m/s². Used for aircraft takeoff acceleration and ship maneuvering specifications. Fighter jets achieve 5-10 kn/s during catapult launch.
