Foot-pound per second to Milliwatt Conversion Formula

To convert from Foot-pound per second (ft-lb/s) to Milliwatt (mW), use the following formula:

Milliwatt (mW)

= 10.737562149 × 1000× Foot-pound per second (ft-lb/s)

= 1355.8179488410813229× Foot-pound per second (ft-lb/s)

With 10.737562149 is the ratio between the base units Watt (W) and Foot-pound per second (ft-lb/s).


Example

Let's convert 5 Foot-pound per second (ft-lb/s) to Milliwatt (mW).

Using the formula:

5 × 1355.8179488410813229 = 6779.0897442054066145

Therefore, 5 Foot-pound per second (ft-lb/s) is equal to 6779.0897442054066145 Milliwatt (mW).

How many foot-pounds per second are in one milliwatt? One Milliwatt (mW) contains 0.000737562149 Foot-pounds per second (ft-lb/s) — the inverse of the factor above. Multiplying by 1355.8179488410813229 takes you from foot-pounds per second to milliwatts; multiplying by 0.000737562149 brings you back.

Put in words: one foot-pound per second equals 1355.8179488410813229 milliwatts, so the foot-pound per second is the larger unit of this pair. Converting between them never changes the amount of power being measured — only the size of the unit you count it in.

What is a Foot-pound per second (ft-lb/s)?

A Foot-pound per second (ft-lb/s) is a base unit of power in the imperial system.

The plural form is 'foot-pounds per second'.


How is Power Measured in the Imperial System?

The foot-pound per second (ft-lb/s) is a key unit of power in the Imperial and US customary systems of measurement.

In simple terms, it measures the rate at which work is done or energy is transferred.

Specifically, one foot-pound per second is the power expended when a force of one pound-force moves an object a distance of one foot in one second.


How to Convert Foot-Pounds per Second (ft-lb/s) to HP and Watts

For many practical engineering and physics applications, you'll need to convert ft-lb/s to other common units of power.

The conversion formulas are straightforward:

  • 550 foot-pounds per second is precisely equal to 1 horsepower (hp).
  • 1 foot-pound per second is approximately equal to 1.3558 watts (W), the SI unit of power.

These essential conversions allow for easy comparison and power calculation across different measurement systems.


What is an Example of a Foot-Pound per Second?

The foot-pound per second can be visualized as the power required to counteract gravity by lifting a one-pound object vertically by one foot in the span of one second.

This practical definition illustrates the concept of power as the rate of doing work.

This makes the power calculation a tangible way to understand the output of engines, machines, and other mechanical systems.

What is a Milliwatt (mW)?

A milliwatt (mW) is a unit used to measure power.

It is equal to one-thousandth of a watt.

To put it simply, you need 1,000 milliwatts to equal one watt (1 W = 1,000 mW).


What Are Milliwatts Used For?

The milliwatt (mW) is the perfect unit for measuring the small amount of power used by many common electronic devices.

For example, the power of a Wi-Fi signal, the laser in a Blu-ray player, and the tiny LEDs on your electronics are all measured in milliwatts.

Using such small amounts of power is key to making the batteries last longer in your favorite gadgets, including wireless earbuds, smartwatches, and TV remotes.


How Do You Convert Milliwatts? (mW to Watts and dBm)

While the most common conversion is between milliwatts and watts (1,000 mW = 1 W), some technical fields use a different unit.

In telecommunications and fiber optics, power is often measured in dBm (decibels relative to one milliwatt). This scale makes it easier to work with a vast range of power levels.

For reference, 0 dBm is equal to exactly 1 mW.


Why Milliwatts (mW) Are Important for Laser Safety

When it comes to products with lasers, the milliwatt (mW) rating is a critical safety measure.

To prevent eye injuries, regulatory bodies like the FDA classify lasers based on their power output in milliwatts.

For example, handheld laser pointers sold to the public are legally required in most regions to have a power output of less than 5 mW.

This is a clear example of how milliwatt ratings are used to keep consumers safe.
