One kilowatt is approximately equal to

Options

A. 1.34 hp
B. 1.56 hp
C. 2.50 hp
D. 1.83 hp

Explanation

To solve the question "One kilowatt is approximately equal to how many horsepower (HP)?", we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- We know that 1 horsepower (HP) is defined as 746 watts (W).
- We also know that 1 kilowatt (kW) is equal to 1000 watts.

2. **Convert Kilowatts to Watts**:
- Since we need to convert kilowatts to horsepower, we will first express 1 kW in terms of watts:
\[ 1 \text{ kW} = 1000 \text{ W} \]

3. **Use the Conversion Factor**:
- We know that:
\[ 1 \text{ HP} = 746 \text{ W} \]
- To find out how many horsepower are in 1000 watts, we can set up the following equation:
\[ 1 \text{ kW} = \frac{1000 \text{ W}}{746 \text{ W/HP}} \]

4. **Calculate the Value**:
- Now, we perform the division:
\[ 1 \text{ kW} = \frac{1000}{746} \text{ HP} \]
- Using a calculator, we find:
\[ \frac{1000}{746} \approx 1.34 \text{ HP} \]

5. **Conclusion**:
- Therefore, we conclude that:
\[ 1 \text{ kW} \approx 1.34 \text{ HP} \]

### Final Answer:
1 kW is approximately equal to **1.34 HP**.
