Common Use Cases
-
Calculating mechanical power from torque times rotational speed in US customary units
-
Estimating power output of small motors and hand-operated tools
-
Converting historical mechanical power data to SI-equivalent electrical apparent power
-

Tips & Best Practices
-
Confirm units before conversion to ensure accuracy
-
Use the tool for approximate equivalences especially when relating mechanical to electrical power
-
Consider the power factor when interpreting volt ampere results in AC circuits
-
Apply results carefully in engineering analyses involving both mechanical and electrical systems
Limitations
-
Volt ampere measures apparent power including reactive components; conversion assumes power factor of 1 for equivalence
-
Direct interpretation from mechanical power to apparent electrical power is approximate due to phase angle considerations
-
Does not account for reactive power or power factor variations in real-world AC circuits
Frequently Asked Questions
-
What does one pound-foot per second measure?
-
It measures mechanical power as one pound-force foot of work done per second in Imperial units.
-
What is the meaning of volt ampere?
-
Volt ampere is the unit of apparent power in AC circuits, calculated as root-mean-square voltage times root-mean-square current.
-
Can I directly compare pound-foot/second to volt ampere values?
-
The conversion provides an approximate relation assuming a power factor of 1, but real applications with AC power require considering power factor and phase angles.
Key Terminology
-
Pound-foot/second
-
An Imperial unit of mechanical power equal to one pound-force foot of work performed per second.
-
Volt ampere (V*A)
-
The unit of apparent power in alternating-current circuits, equal to the product of RMS voltage and current.
-
Apparent Power
-
Total power in an AC circuit including both real and reactive components.
