1 kWh = __________ MJ.

Options

A. 36
B. `0.36`
C. `3.6`
D. 360

Explanation

To convert 1 kWh to MegaJoules (MJ), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Units**:
- 1 kWh (kilowatt-hour) is a unit of energy. It represents the energy consumed by a 1 kW device running for 1 hour.

2. **Convert kWh to Joules**:
- 1 kWh = 1000 watt-hours.
- Since 1 watt = 1 Joule/second, we need to convert hours into seconds to express this in Joules.
- 1 hour = 3600 seconds.
- Therefore, 1 kWh = 1000 watts × 3600 seconds = 3,600,000 Joules (or 3.6 × 10^6 Joules).

3. **Convert Joules to MegaJoules**:
- 1 MegaJoule (MJ) = 10^6 Joules.
- To convert Joules to MegaJoules, we divide the number of Joules by 10^6.
- So, 3,600,000 Joules = 3,600,000 / 1,000,000 MJ = 3.6 MJ.

4. **Final Result**:
- Therefore, 1 kWh = 3.6 MJ.

### Final Answer:
1 kWh = 3.6 MJ.
