Miles per hour

Mile per hour is a unit of speed defined in the Imperial and US customary systems of units. It measures the number of miles an object travels within an hour. International mile [mi] is a unit of length, equal to 5280 feet and precisely defined as 1609.344 meters. The symbol more commonly used on signs and labels is the abbreviation mph, however in science and engineering contexts, mi/h may be more convenient for unit arithmetic.

The relationships between the miles per hour and some other speed units, native to the Imperial/US customary and SI systems, are shown in the following table:

Feet per second

Foot per second is a unit of speed defined in the Imperial and US customary systems of units. It measures the number of feet an object travels within a second. Foot [ft] is a unit of length, precisely defined as equal to 0.3048 meters.

The relationships between the foot per second and some other speed units, native to the Imperial/US customary and SI systems, are shown in the following table:

Kilometers per hour km/h \frac{1}{3.6\cdot 0.3048}\approx 0.91134

How to convert miles per hour to feet per second

  • Multiply speed in mph with 5280
  • Divide the result by 3600
  • The result is the speed in feet per second

For example 60 mph is: 60x5280/3600 = 88 fps

How to convert feet per second to miles per hour

  • Multiply speed in fps with 3600
  • Divide the result by 5280
  • The result is the speed in mph

For example 99 fps is: 99*3600/5280 = 67.5 mph

What is 1 mile per hour equal to in feet per second?

Since by definition 5280 feet equal one mile, and an hour has 3600 seconds, through simple calculation we can reach the conclusion that 1.466667 feet per second equal one mile per hour (5280/3600).

How many seconds are in 1 mph?

1 Mile per Hour: A distance of one international mile or 1 760 international yards or exactly 1609.344 meters travelled in one hour or exactly 3 600 seconds.

How many feet do you travel at 1 mph?

1 mph = 88 ft/min 1 mile per hour is 88 feet per minute.

How many feet is 60 mph?

So if you want to calculate the speed of a car at sixty miles an hour, the math is (60 x 5280) ÷ (60 x 60) = 88 feet per second.
