Convert Speed from Foot Per Minute to Mile Per Hour (ft/min to mph)

Foot per minute to Mile per hour Conversion Formula

To convert from Foot per minute (ft/min) to Mile per hour (mph), use the following formula:

Example

Let's convert 5 Foot per minute (ft/min) to Mile per hour (mph).

Using the formula:

Therefore, 5 Foot per minute (ft/min) is equal to $0.056818$ Mile per hour (mph).

What Are Feet Per Minute (ft/min)?

Feet per minute (ft/min or FPM) is a unit used to measure speed, typically for objects moving slower than a car.

It tells you how many feet something travels in one minute.

For a quick comparison, 1 ft/min is equal to about 0.011 mph.

How to Convert Feet Per Minute

Converting feet per minute (ft/min) into more familiar units, like miles per hour (mph) or feet per second (ft/s), makes the measurement easier to understand.

The conversion is simple:

• To convert ft/min to mph: Divide the ft/min value by 88.
• To convert ft/min to feet per second (ft/s): Divide the ft/min value by 60.

For example, a brisk walking pace of 264 ft/min is equal to exactly 3 mph (264 ÷ 88 = 3).

Practical Uses for Feet Per Minute

Although it's not used for driving, feet per minute (ft/min) is an essential unit across many industries where precision and safety matter.

HVAC and airflow

In HVAC work, technicians measure air velocity using anemometers in feet per minute (ft/min).

That number is then used to calculate the total airflow in cubic feet per minute (CFM), ensuring that ducts deliver the right amount of ventilation and the system runs efficiently.

Manufacturing and industrial safety

Ft/min is also a common way to express the speed of equipment, such as conveyor belts, production lines, and machine tools.

Controlling those speeds precisely improves efficiency and product quality — and it keeps workers safer.

Safety organizations, such as OSHA, often set maximum operating speeds in feet per minute to help prevent accidents.

Understanding Miles Per Hour (MPH)

Miles per hour (mph) is a standard unit of speed that measures the distance traveled in one hour.

It is primarily used in countries that use the imperial system of measurement, such as the United States and the United Kingdom, where it is commonly seen on road signs and speedometers.

How to Convert MPH to Other Speeds

When comparing speeds across countries, it helps to convert miles per hour (mph) into other common units.

One mile per hour equals:

• 1.609 kilometres per hour (km/h)
• 0.447 metres per second (m/s)
• 1.47 feet per second (ft/s)

These conversions are helpful for a wide range of applications, including international travel, science, and engineering.

Where Did MPH Come From?

The use of miles per hour became popular with the rise of cars and trains.

Before modern vehicles, travel was slow and didn't require precise speed measurement. As cars became common in the late 19th and early 20th centuries, MPH became the standard for speedometers in countries using the imperial system, providing drivers with a simple way to measure their speed.

Which Countries Use MPH?

While most of the world uses kilometres per hour (km/h) from the metric system, a few countries still officially use miles per hour.

The most well-known are:

• The United States
• The United Kingdom
• Liberia
• Myanmar

This is why many car speedometers show both MPH and km/h, making them useful for drivers in different parts of the world.
