Kilowatt to Kilowatt Hour Calculator

Energy Formula:

\[ E_{kWh} = P_{kW} \times t \]

Energy (E): kWh

Definition: This calculator converts power in kilowatts (kW) to energy in kilowatt-hours (kWh) based on the duration of usage.

Purpose: It helps determine electrical energy consumption for billing, system sizing, or energy efficiency analysis.

The calculator uses the formula:

\[ E_{kWh} = P_{kW} \times t \]

Where:

Explanation: Energy is simply power multiplied by time. One kilowatt-hour equals one kilowatt of power used for one hour.

Details: Utility companies bill customers based on kWh consumption. This conversion helps estimate electricity costs and compare energy usage.

Tips: Enter the power in kilowatts and the time duration in hours. Both values must be ≥ 0.

Q1: What's the difference between kW and kWh?
A: kW measures power (rate of energy use), while kWh measures energy (total consumption over time).

Q2: How do I convert watts to kilowatts?
A: Divide watts by 1000 (1 kW = 1000 W).

Q3: Can I use minutes instead of hours?
A: Yes, but convert minutes to hours (divide by 60) before calculation.

Q4: What's a typical kWh consumption for a home?
A: Average U.S. household uses about 877 kWh per month (29 kWh/day).

Q5: How does this relate to electricity cost?
A: Multiply kWh by your utility's rate (e.g., 10 kWh × $0.12/kWh = $1.20).
