What does nanojoule/second measure?

It measures power as energy transfer at the nanowatt scale, suitable for very small continuous power levels.

What is a volt ampere used for?

Volt ampere is a unit of apparent power in AC circuits, representing the total power delivered regardless of phase angle.

Can I convert any power value between nJ/s and V*A?

While mathematically convertible, nanojoule/second values are very small and volt ampere values usually describe larger apparent power, so practical equivalence depends on context.

Examples

1 nJ/s is equal to 0.000000001 V*A
500 nJ/s converts to 5e-7 V*A
These examples illustrate converting very small power levels to apparent power units typical in AC circuits

Common Use Cases

Specifying power consumption in ultra-low-power sensors and IoT devices
Expressing average power in microelectronics where energy per operation times frequency is used
Describing optical power in low-energy photonics or single-photon experiments
Rating transformers and UPS by their apparent power capacity
Electrical engineering tasks distinguishing apparent power from real and reactive power in AC systems

Tips & Best Practices

Confirm the context of measurement to ensure correct interpretation of nanojoule/second values
Use the converter to integrate very small power data into larger electrical system analyses
Be aware that volt ampere represents apparent power which depends on power factor and phase angle
Use conversions for comparing or sizing electrical equipment when phase conditions are relevant

Limitations

Nanojoule/second measures extremely small power, whereas volt ampere typically refers to larger apparent power values
Volt ampere unit reflects apparent power influenced by power factor and phase angle, not only instantaneous energy transfer
Direct practical equivalence between these units is limited due to differing measurement contexts and scales
