US Standard Speed (Velocity)

These are the most common measurements:



Speed in feet per second (fps)

If something is traveling at 1 fps it moves 1 foot every second.

It is a very slow walking pace.

An hour and a half at 1 fps moves you about 1 mile.

Speed in miles per hour (mph)

If something is traveling at 1 mph it moves 1 mile every hour.

It is a slow walking pace.

One hour walking at 1 mph moves you 1 mile.

Miles per hour is often used for car speeds.

Example: Highway speed is around 60 mph

One minute at 60 mph will move you 1 mile.


You can convert from fps to mph:

Example: What is 60 mph in fps?

A mile has 5,280 feet, and an hour has 3,600 seconds, so 60 miles per hour is:

60 mph = 88 fps


Velocity is speed with a direction.

So if something is moving at 5 mph that is a speed.

But if you say it is moving at 5 mph westwards that is a velocity.

If something moves backwards and forwards very fast it has a high speed, but a low (or zero) velocity
