What is an erg per second (erg/s)?

An erg per second is a CGS unit of power defined as one erg of energy transferred per second, equal to 1×10⁻⁷ watts in the SI system.

What does volt ampere (V*A) represent?

Volt ampere is the unit of apparent power in AC circuits, calculated by multiplying the root-mean-square voltage and current, and equals watts only when the power factor is 1.

Why convert erg/s to volt ampere?

The conversion helps relate astrophysical or theoretical CGS power units to electrical apparent power measurements used in engineering and system design.

Common Use Cases

Translating astrophysical radiative power units into electrical apparent power measures.
Determining transformer and UPS capacity in terms of apparent power for AC circuits.
Bridging theoretical power data expressed in CGS units with engineering power ratings.
Specifying and sizing electrical distribution equipment with appropriate power values.

Tips & Best Practices

Remember that erg/s is a CGS unit and typically replaced by watts in SI usage.
Use conversion results considering that volt ampere represents apparent power, not necessarily real power.
Account for very small erg/s values when converting, as typical electrical power ratings are much larger.
Verify power factor in AC systems to interpret VA values correctly relative to actual power.

Limitations

Conversion assumes equivalence between watts and volt ampere only in resistive circuits with power factor equal to 1.
Volt ampere measures apparent power, which may not reflect reactive power components in AC systems.
Erg per second values are extremely small compared to typical electrical power, requiring careful scale handling.
Direct conversion does not account for difference between real and reactive power in practical systems.
