Seconds to meters per second (exhaust velocity)
Type a value in s to get it in m/s instantly.
3,432.328m/s
That's 1.01× as efficient as a Merlin vacuum engine, while a Space Shuttle main engine in vacuum is 1.29× more efficient. Its exhaust leaves at about 3.432 km/s.
Convert the other way: m/s to s
What it means
How efficient is that engine?
Rocket figures are typical published values, at sea level unless marked vacuum. The jet-engine figure is for an airliner at cruise.
The math
How to convert s to m/s
To convert seconds to meters per second (exhaust velocity), multiply by 9.80665.
Example: 350 s × 9.80665 = 3,432.33 m/s.
In the other direction, 1 m/s = 0.101972 s.
