That is sort of like asking how many miles per hour does 100 horsepower equal. Ft lbs is energy, and FPS is speed. There IS a formula to calculate the energy (in foot lbs) of a bullet, but to use that, you need to know SPEED in FPS, and WEIGHT (in grains) of the bullet. A 40 grain bullet at 1000 fps is pretty weak. A 400 gr bullet at 1000 fps can drop a moose.
It depends on several factors, but it can as little as 700 FPS, or as high as 1500 FPS, however, the average is closer to 1000. Most (but not all) 9mm ammo travels faster than 1000.
You are mixing apples and Tuesday FPS refers to feet per second or how fast a projectile is travelling. ft lbs refers to a measurement of recoil.
62 mph = 90.933... fps
15 fps (feet / second) = 10.23 mph
It depends on the cartridge specifications and what gun it is shot from (the barrel length). Generally speaking, you can get between about 700 FPS (the very low end) to about 1200 (the very high end, normally with lighter bullet weight. However, more commonly, it will be between 850 and 1000 FPS.
1000+

About 1000 fps for a pre-charged pneumatic, such as the Evanix.
It depends on several factors. .380 ammo generally runs from around 700 FPS up to about 1000 FPS depending on the specifications of the particular cartridge and the barrel length of the gun.
@ 1000 fps
Crosman says it's rated at 1000 FPS.
between about 1000 FPS and 1800 FPS, depending on the cartridge specifications and the length of the barrel is it fired from.
6600 fps
275 fps
can vary from 1000-2500 fps or more
Convert 3000 fps to mph
It depends on the load and bullet weight, but usually somewhere between 1000 and 1500 FPS.
