KVA to KW Calculator

Enter any two values (KVA, KW, or Power Factor) into the KVA to KW Calculator, and it will compute the missing value based on the relationship between these variables.

The KVA to KW Calculator is a powerful tool to convert between kilovolt-amperes (KVA) and kilowatts (KW). KVA represents apparent power, while KW represents real power, and the conversion depends on the Power Factor (PF). This calculator is ideal for electrical engineers, electricians, and anyone working with power systems to ensure accurate measurements and efficient energy usage.

Formula

\text{KW} = \text{KVA} \times \text{Power Factor}

Alternatively, to find other values:

\text{KVA} = \frac{\text{KW}}{\text{Power Factor}}

\text{Power Factor} = \frac{\text{KW}}{\text{KVA}}

Variable	Description	Units
KVA	Apparent power	W, kW, MW
KW	Real power	W, kW, MW
Power Factor	Efficiency ratio (0 to 1)	Decimal, Percent

Solved Calculations

Example 1:
Calculate KW when KVA = 50 and PF = 0.8.

Input	Value
KVA	50
Power Factor	0.8
KW	$50 \times 0.8 = 40 \,$

Example 2:
Calculate Power Factor when KVA = 20 and KW = 16.

Input	Value
KVA	20
KW	16
Power Factor	$16 \div 20 = 0.8 \, \text{(d$
