So, if we want to know how many revolutions our wheels have to turn, we divide 200 centimeters by 24.92 centimeters/revolution (remember the circumference is how far the wheel goes in one revolution). This is also how far the circle rolls on flat ground in one rotation. For our example muzzle velocity of 2000 feet per second, multiplying by 12 gives 2000 x 12 = 24,000 inches per second. The cookie is used to store the user consent for the cookies in the category "Analytics". Hence, we should look for a quantity whose units are metres / revolution.
