Convert Kilowatts To Horsepower (kW to HP Calculator)

Kilowatt to horsepower conversion is one of the most common ones.

Here’s how you can convert kW to HP:

1 kW = 1.341 HP

The easiest way to remember the kW to HP conversion formula is to remember how many kilowatts is 1 horsepower of energy:

1 HP = 3/4 kW

We’ll convert kW to HP for 3 examples further on:

• For an average 110 kW gas car (Example 1)
• 48,000 BTU 5-zone mini-split air conditioner (Example 2)
• We’ll calculate how many HP new Tesla S model has (Example 3)

Use this handy converted to calculate how many HP is a given number of kW:

kW to HP Table

We’ve calculated some kilowatt to horsepower conversion, and gathered them in the table here:

Example 1: Average 110 kW Gas Car

Let’s take a normal 110 kW car as an example. It is powered by 110 kW. How many HP is that? Let’s calculate:

Here’s how to convert 110 kW to HP:

Number of HP = 110 kW * 1.341 = 147.51 HP

The average 110 kW car has about 150 horsepower.

Example 2: 48,000 BTU 5-Zone Mini-Split Air Conditioner

Mini-split air conditioners pack quite a lot of power. A 48,000 BTU 5-zone air conditioner by Mitsubishi or Carrier can easily generate 24 kW of power.

Let’s calculate how many HP is 24 kW for an air conditioner:

As we can see, an air conditioner can have 30+ HP. Here’s how you can convert kW to HP by hand:

Number of HP = 24 kW * 1.341 = 32.18 HP

You can use this kW to HP equation for smaller (12,000 BTU, 24,000 BTU, 36,000 BTU) and bigger (60,000 BTU) air conditioners.

Example 3: How Many HP Does A Tesla S Model Have?

In gas-powered cars, we always talk about horsepower. For electric cars, we usually use kilowatts.

Tesla S, for example, can produce 270 kW. How many HP is that:

270 kW Tesla S can produce more than 360 HP.
