Energy Formula:
From: | To: |
Definition: This calculator converts power in kilowatts (kW) to energy in kilowatt-hours (kWh) by multiplying by time in hours.
Purpose: It helps determine energy consumption or production over time, useful for electricity billing, solar power calculations, and energy management.
The calculator uses the formula:
Where:
Explanation: Energy is simply power multiplied by time. 1 kWh equals 1 kW of power used for 1 hour.
Details: Utility companies bill in kWh, making this conversion essential for understanding energy costs and consumption patterns.
Tips: Enter the power in kW and time in hours. Both values must be positive numbers.
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 calculate kWh for minutes instead of hours?
A: Convert minutes to hours (divide by 60) before using the calculator.
Q3: Can I use this for solar panel calculations?
A: Yes, multiply your solar array's kW rating by hours of sunlight to estimate daily kWh production.
Q4: How many kWh is 1 kW for 24 hours?
A: 24 kWh (1 kW × 24 h = 24 kWh).
Q5: Why is my electric bill in kWh?
A: Utilities charge for total energy consumed, not instantaneous power, making kWh the appropriate unit.
