Convert Kilowats To Horsepower: Insert kW, Get HP

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:

Kilowatts (kW) Horsepower (HP)
1 kW to HP: 1.34 HP
2 kW to HP: 2.68 HP
3 kW to HP: 4.02 HP
4 kW to HP: 5.36 HP
5 kW to HP: 6.71 HP
7.5 kW to HP: 10.06 HP
10 kW to HP: 13.41 HP
20 kW to HP: 26.82 HP
30 kW to HP: 40.23 HP
40 kW to HP: 53.64 HP
50 kW to HP: 67.05 HP
55 kW to HP: 73.76 HP
75 kW to HP: 100.58 HP
77 kW to HP: 103.26 HP
85 kW to HP: 113.99 HP
100 kW to HP: 134.10 HP
110 kW to HP: 147.51 HP
125 kW to HP: 167.63 HP
130 kW to HP: 174.33 HP
132 kW to HP: 177.01 HP
140 kW to HP: 187.74 HP
147 kW to HP: 197.13 HP
150 kW to HP: 201.15 HP
160 kW to HP: 214.56 HP
170 kW to HP: 227.97 HP
180 kW to HP: 241.38 HP
200 kW to HP: 268.20 HP
220 kW to HP: 295.02 HP
240 kW to HP: 321.85 HP
250 kW to HP: 335.26 HP
300 kW to HP: 402.31 HP
350 kW to HP: 469.36 HP
400 kW to HP: 536.41 HP
450 kW to HP: 603.46 HP
500 kW to HP: 670.51 HP

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.
