Enter the apparent power in kilovolt-amperes and the power factor into the calculator to determine the power in watts; this calculator can also evaluate any of the variables given the others are known.

## Kva To Watts Formula

The following formula is used to calculate the power in watts (W) from the apparent power in kilovolt-amperes (kVA).

P = S * PF

Variables:

- P is the power in watts (W)
- S is the apparent power in kilovolt-amperes (kVA)
- PF is the power factor

To calculate the power in watts, multiply the apparent power in kilovolt-amperes by the power factor.

## What is a Kva To Watts?

KVA (Kilovolt-Ampere) and Watts are both units of power, but they measure different types of power. KVA is a unit of apparent power, which includes both the real power (measured in watts) and the reactive power (which is not used, but is necessary to maintain the voltage levels in the system). The relationship between KVA and Watts is defined by the power factor of the electrical system. The power factor, which ranges from 0 to 1, represents the percentage of the electricity that is being used to do useful work. If the power factor is 1, then all the power is being used effectively, and the KVA is equal to the Watts. However, if the power factor is less than 1, then some of the power is being wasted, and the KVA will be greater than the Watts. Therefore, the conversion from KVA to Watts depends on the power factor and is calculated by multiplying the KVA by the power factor.

## How to Calculate Kva To Watts?

The following steps outline how to convert Kva to Watts:

- First, determine the apparent power in Kva (Kilovolt-ampere).
- Next, determine the power factor (PF).
- Multiply the apparent power (Kva) by the power factor (PF) to get the real power in Kilowatts (KW).
- Finally, calculate the power in Watts by multiplying the real power (KW) by 1000.

**Example Problem:**

Use the following variables as an example problem to test your knowledge:

Apparent power (Kva) = 5

Power factor (PF) = 0.8
