What does volt ampere measure?

Volt ampere measures apparent power in AC circuits, calculated as the product of root-mean-square voltage and current, representing total delivered power regardless of phase angle.

Why convert volt ampere to Btu (IT)/second?

Converting volt ampere to Btu (IT)/second helps translate electrical apparent power into thermal power units useful for heat transfer, energy balance, and HVAC design.

How to Convert from Volt ampere [V*A] to Btu (IT)/second [Btu/s]

Q: Does 1 volt ampere equal 1 watt?

No, 1 volt ampere equals watts only if the power factor is 1; otherwise, volt ampere measures apparent power which can differ from real power in watts.

Tips & Best Practices

Be mindful that volt ampere measures apparent power, which may differ from real power based on power factor
Use this conversion when translating electrical power ratings into thermal energy equivalents
Consult equipment specifications to understand whether electrical or thermal measurements are more appropriate
Consider system efficiencies and phase angles when applying conversions for energy management
Use the provided formula and examples to verify manual calculations

Limitations

Volt ampere units represent apparent electrical power and do not always equal real power (watts)
Btu (IT)/second measures heat power, so direct conversion may not reflect exact real power without accounting for load and efficiency
Conversion accuracy depends on knowing system power factor and operational context
The tool does not account for phase angle or thermal system losses
Use caution when applying conversions in systems where precise thermal or electrical power measurement is critical
