The kWh to Amps Calculator is a valuable tool used in electrical engineering and everyday household applications to convert energy consumption from kilowatt-hours (kWh) to amperes (A), which represent the current flowing through a circuit. This conversion is essential for understanding the electrical load and ensuring the safety and efficiency of electrical systems.
Formula of kWh to Amps Calculator
The formula used by the kWh to Amps Calculator is:
I = (1000 × kWh) ÷ (Voltage × Hours)
Where:
- I is the current in amps,
- kWh is energy in kilowatt-hours,
- Voltage is the voltage in volts,
- Hours is the duration over which the energy is consumed in hours.
This formula calculates the amperage (current) based on the energy consumption in kilowatt-hours and the voltage of the electrical system.
Table of General Terms
| kWh | Voltage (V) | Amps (A) |
|---|---|---|
| 1 | 120 | 8.33 |
| 2 | 120 | 16.67 |
| 3 | 120 | 25 |
| 4 | 120 | 33.33 |
| 5 | 120 | 41.67 |
| 6 | 120 | 50 |
| 7 | 120 | 58.33 |
| 8 | 120 | 66.67 |
| 9 | 120 | 75 |
| 10 | 120 | 83.33 |
Example of kWh to Amps Calculator
Suppose we have an electrical appliance that consumes 3 kWh over 2 hours and is connected to a voltage source of 120 volts. We can use the updated formula to find the amperage.
Using the formula:
Amps (A) = (1000 × kWh) ÷ (Voltage × Hours)
Substituting the values:
Amps (A) = (1000 × 3) ÷ (120 × 2) = 25 Amps
So, the appliance draws approximately 25 amps of current from the power source.
Most Common FAQs
A: The purpose of the kWh to Amps Calculator is to convert energy consumption from kilowatt-hours to amperes, providing valuable information for electrical system design, safety, and efficiency.
A: Yes, the calculator can be used for both alternating current (AC) and direct current (DC) circuits, as long as the voltage and energy consumption values are correctly inputted.
A: Knowing the amperage of an electrical device helps determine the appropriate wire size, circuit breaker rating, and overall electrical load, ensuring safe and efficient operation of the electrical system.
I think you are converting kW to Amps not KWh. This page is somewhat misleading.
Thank you for your comment! You were right — the page was misleading as it was converting kilowatts (kW) to amps, not kilowatt-hours (kWh). We’ve now updated the formula and the calculator to correctly calculate amps based on energy (kWh), voltage, and time (hours). Your feedback was very helpful, and the page should now be accurate. Thanks again for helping improve our content!
