Practical Example

Scenario: A 1200W microwave is used 1 hour per day for 30 days. Electricity rate: $0.14 per kWh.

Inputs:

  • Power Rating: 1200W (1.2 kW)
  • Duration: 1 hour/day × 30 days = 30 hours
  • Electricity Rate: $0.14/kWh

Output Using Kwh Calculator:

  • Energy Consumption: 1.2 kW×30 h=36 kWh1.2 \text{ kW} \times 30 \text{ h} = 36 \text{ kWh}1.2 kW×30 h=36 kWh
  • Estimated Cost: 36 kWh×0.14=$5.0436 \text{ kWh} \times 0.14 = \$5.0436 kWh×0.14=$5.04

This allows users to anticipate energy usage and manage electricity costs effectively.
