One of the most frequently needed electricity conversions is kW (kilowatts) to Amps.
- kW is a unit of measure of electrical power (wattage).
- Ampere (A) is a unit of measure of electrical current (amperage).
To convert kW to Amps, we can use the equation for electrical power:
Power (kW) = I (A) * V (V)
You can use this kilowatt to amperes converter. Below you will find 3 examples of a kW to Amps conversion for:
- 4 kW central air conditioner (220 V).
- 1 kW washing machine (220 V).
- 36 kW tankless electric water heater (240 V).
kW To Amps Calculator
Using the calculator, we have calculated a kW to Amps table:
|Power (kW)||Voltage (220 V)||Amperage (A)|
|1 kW to Amps:||220 V||4.55 Amps|
|2 kW to Amps:||220 V||9.09 Amps|
|4 kW to Amps:||220 V||18.18 Amps|
|6 kW to Amps:||220 V||27.27 Amps|
|9 kW to Amps:||220 V||40.91 Amps|
|18 kW to Amps:||220 V||81.82 Amps|
|27 kW to Amps:||220 V||122.73 Amps|
|36 kW to Amps:||220 V||163.64 Amps|
|45 kW to Amps:||220 V||227.27 Amps|
Example 1: How Many Amps Does 4 kW Central AC Unit Draw?
For example, let’s take a 36,000 BTU central air conditioner with a power output of 4 kW. The electrical circuit can provide 220 V voltage. How many amps does the 4 kW AC unit draw? Let’s use the kW to Amps calculator:
We can see that the 4 kW air conditioner needs 18.18 amps to function properly.
Example 2: 1 kW Washing Machine To Amps
Most washing machines draw about 1,000 W or 1 kW of electrical power. You don’t need upgrades to your electrical circuit for an average washing machine. Here is how many amps it draws:
1 kW washing machine needs about 4.55 Amps to run.
Example 3: 36 kW Electrical Tankless Water Heater
Tankless water heaters are notorious for needing a huge amount of electrical current (amps). For example, you have 9 kW, 18 kW, 27 kW, and even 36 kW tankless water heaters that run on electricity. Usually, they run on 240 V and can reach up to 200 amps.
For this example, let’s take a bigger 36 kW tankless water heater on 240 V potential:
As you can see, 36 kW converts to 150 amps. This is some serious amperage; for such a device, you would need 4 x 40 A breakers.
