VA to Watts Calculator
Convert Volt-Amperes (VA) to Watts for accurate power calculations in your campervan electrical system
Value between 0 and 1 (typically 0.8)
What is VA?
VA (Volt-Amperes) is the apparent power in an electrical circuit. It's the product of voltage and current, without considering the phase difference.
What are Watts?
Watts represent real power - the actual power consumed by your appliances and converted into useful work (heat, light, motion, etc.).
Power Factor Explained
Power factor is the ratio of real power (Watts) to apparent power (VA). It ranges from 0 to 1, where:
- • 1.0 = Perfect efficiency (resistive loads)
- • 0.8 = Typical for most appliances
- • 0.6-0.7 = Motors and inductive loads
For Campervan Systems
When sizing inverters, use a power factor of 0.8 for mixed loads. This ensures your system can handle the actual power requirements.
Watts = VA × Power Factor
Real Power = Apparent Power × Efficiency Ratio
Example 1
3000 VA × 0.8 = 2400 Watts
Example 2
2000 VA × 1.0 = 2000 Watts
Example 3
1500 VA × 0.6 = 900 Watts
