What does volt ampere (V*A) measure?

Volt ampere is the unit of apparent power in AC circuits, calculated as the product of RMS voltage and RMS current, and represents total power without considering phase angle.

When should I use calorie (th)/hour as a power unit?

Calorie (th)/hour is used to measure small heat transfer rates, often in calorimetry, metabolic heat production, and low-level thermal applications.

Does 1 volt ampere always equal 860.4206500956 cal (th)/h?

Yes, for this conversion the relation is fixed, but the interpretation depends on the load's power factor and whether all apparent power is converted to heat.

Browser-based and simple to use with clear input and output fields.
Supports conversions used in electrical engineering and thermal science.

Examples

Convert 2 V*A to cal (th)/h results in 1720.8413 cal (th)/h.
Convert 0.5 V*A to cal (th)/h results in 430.2103 cal (th)/h.

Common Use Cases

Translating electrical apparent power into equivalent thermal power rates for heat transfer analysis.
Using in laboratory calorimetry for chemical reactions or sample heat measurements.
Reporting metabolic heat production where power is expressed in calories per hour.
Sizing electrical equipment while considering heat effects in devices.

Tips & Best Practices

Confirm that apparent power measurements correspond to conditions where electrical power converts effectively to heat.
Use the tool for small heat transfer rates where the thermochemical calorie unit is appropriate.
Consider power factor when interpreting results, as VA includes reactive components.
Cross-check unit suitability for your specific engineering or scientific context.

Limitations

Volt ampere (VA) represents apparent power and may not equal actual heat produced due to power factor effects.
Calorie (th)/hour is a non-SI unit that measures very small thermal power values and may not fit all applications.
The conversion assumes all electrical apparent power converts fully to heat, which may not be the case in reactive or inductive circuits.
