3.193s
That's 5× as high as a 10 m diving board, while Niagara Falls is 1.02× higher. Without air it falls in 3.193 s and hits at 112.7 km/h (70.04 mph).
Convert the other way: s to ft
What it means
How high is that drop?
In a vacuum on Earth (g = 9.80665 m/s²). Air resistance matters for long falls: a skydiver tops out near 200 km/h.
The math
How to convert ft to s
t = √(2h ÷ g), v = √(2 g h), with g = 9.80665 m/s²; h = ½ g t².
Example: 164 ft = 3.19289 s.
