16 Amps to kW
16 A is 3.68 kW at 230 V and 1.92 kW at 120 V (single-phase, power factor 1). Table for DC and three-phase, power factor 0.8, and the formula.
Formula
Worked example
- P = 230 × 16 × 1 / 1,000 = 3.68 kW
- With a power factor of 0.9: P = 230 × 16 × 0.9 / 1,000 = 3.312 kW
On other supplies
| Supply | Voltage | Power at pf 1 | Power at pf 0.8 |
|---|---|---|---|
| DC | 12 V | 0.192 kW | not used |
| DC | 24 V | 0.384 kW | not used |
| DC | 48 V | 0.768 kW | not used |
| Single-phase | 120 V | 1.92 kW | 1.536 kW |
| Single-phase | 230 V | 3.68 kW | 2.944 kW |
| Single-phase | 240 V | 3.84 kW | 3.072 kW |
| Three-phase | 208 V | 5.764 kW | 4.611 kW |
| Three-phase | 400 V | 11.09 kW | 8.868 kW |
| Three-phase | 415 V | 11.5 kW | 9.201 kW |
| Three-phase | 480 V | 13.3 kW | 10.64 kW |
Three-phase rows use the line-to-line voltage. DC ignores the power factor.
What 16 A looks like
16 A is a common miniature circuit breaker rating in IEC-style systems.
This is an estimate of the load current only. Choosing a cable or a breaker also needs the installation method, the ambient temperature, the voltage drop and the rules you work to.
Frequently asked questions
How many kilowatts is 16 amps?
16 A is 3.68 kW on a 230 V single-phase supply and 1.92 kW on 120 V, both with a power factor of 1. The power depends on the voltage, so it is a different answer on every supply.
What if the power factor is not 1?
The real power falls. At 230 V and a power factor of 0.9, 16 A is 3.312 kW. Heaters and filament lamps are close to 1, while motors and many power supplies are lower.
What about a three-phase supply?
16 A on 400 V three-phase at a power factor of 0.8 is 8.868 kW. The line voltage is used with the factor √3 (about 1.732).
