Amps to kWh Formula:
From: | To: |
The Amps to kWh formula calculates energy consumption in kilowatt-hours from electrical current (amps), voltage (volts), and time (hours). It provides an accurate measurement of electrical energy usage for various applications.
The calculator uses the Amps to kWh formula:
Where:
Explanation: The formula calculates power consumption by multiplying current, voltage, and time, then converting from watt-hours to kilowatt-hours.
Details: Accurate kWh calculation is crucial for energy consumption monitoring, electricity billing, energy efficiency analysis, and electrical system design.
Tips: Enter current in amps, voltage in volts, and time in hours. All values must be valid positive numbers.
Q1: Why divide by 1000 in the formula?
A: The division by 1000 converts watt-hours to kilowatt-hours, as 1 kilowatt equals 1000 watts.
Q2: Can I use this for DC and AC circuits?
A: This formula works for DC circuits. For AC circuits, you may need to consider power factor for accurate calculations.
Q3: What are typical amp values for household appliances?
A: Typical values range from 0.5A for small electronics to 15-20A for major appliances like air conditioners or electric heaters.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise for the given inputs. Accuracy depends on the precision of your measured values.
Q5: Can this be used for three-phase systems?
A: For three-phase systems, you would need to multiply by √3 (approximately 1.732) in the formula to account for the three phases.
