Foot-pounds per second to Milliwatts conversion

How to convert foot-pounds per second to milliwatts?

To convert from foot-pounds per second (ft·lb/s) to milliwatts (mW), you need to understand the relationship between these units of power. Let's break it down step-by-step.

Conversion Steps:

1. Understand the Units:

   • 1 foot-pound per second (ft·lb/s) is a measure of power, which tells you how much work is done per unit time.
   • 1 Watt (W) is equal to 1 Joule per second (J/s).
   • 1 milliwatt (mW) is equal to 0.001 Watts or 1/1000 Watts.

2. Unit Conversion Factors:

   • 1 foot-pound-force is equivalent to approximately 1.35582 Joules (J).
   • Therefore, 1 foot-pound per second (ft·lb/s) is equivalent to 1.35582 Joules per second (J/s), which is also 1.35582 Watts (W).

3. Convert Watts to Milliwatts:

   • Since 1 Watt is 1000 milliwatts, we multiply by 1000 to convert watts to milliwatts.

Putting it all together: 1 \text{ ft·lb/s} = 1.35582 \text{ W} $1.35582 \text{ W} \times 1000 = 1355.82 \text{ mW}$

So, 1 foot-pound per second is equivalent to 1355.82 milliwatts.

Real-World Examples:

1. A Typical Business Laptop Charger:

   • A business laptop may draw power around 65 Watts (W).
   • 65 W is equal to \frac{65}{1.35582} \approx 47.94 \text{ ft·lb/s}.

2. A Standard Incandescent Light Bulb:

   • An old-fashioned incandescent light bulb may use about 60 Watts (W).
   • 60 W is equal to \frac{60}{1.35582} \approx 44.23 \text{ ft·lb/s}.

3. Microwave Oven:

   • A standard microwave oven typically uses about 1000 Watts (1 kW).
   • 1000 W is equal to \frac{1000}{1.35582} \approx 737.56 \text{ ft·lb/s}.

These examples show that common electrical devices and appliances can use power measured in foot-pounds per second when converted from their standard ratings in watts or kilowatts.
