How Many Amps is 2000 Watts - 2000 Watts to Amps
Conversion from Amps to Watts cannot be done directly without introducing the third unit - volts.
That's why when somebody asks how many Amps is 2000 Watts, one has to respond with the question "at what volts?".

Little Bit of Theory
In order to calculate current in Amps, one has to use the formula:
I(A) = P(W) / U(V)
where:
- I(A): current given in Amps,
- P(W): power given in Watts,
- U(V): voltage (potential difference) given in volts.
Note: this is a very simple formula, assuming that the current is either DC (Direct Current) or the current is AC (Alternate Current) with the phase shift of zero degrees - otherwise, we would have to calculate both "real power" and "reactive power".
Now, if we want to convert 2000 watts to Amps, we have:
I(A) = 2000W / U(V)
The following Watts to Amps conversion table lists power, currents, and voltages of specific loads:
| Power (HP) | Power (W) | Current @ Nominal Voltage | ||||
| 12 Volts | 24 Volts | 36 Volts | 120 Volts | 230 Volts | ||
| 0.335 HP | 250 W | 20.83 A | 10.41 A | 6.94 A | 2.083 A | 1.087 A |
| 0.67 HP | 500 W | 41.67 A | 20.83 A | 13.89 A | 4.167 A | 2.174 A |
| 1 HP | 746 W | 62.16 A | 31.08 A | 20.72 A | 6.216 A | 3.243 A |
| 1.34 HP | 1000 W | 83.33 A | 41.66 A | 27.78 A | 8.333 A | 4.238 A |
| 1.5 HP | 1119 W | 93.25 A | 46.62 A | 31.08 A | 9.325 A | 4.865 A |
| 2 HP | 1492 W | 124.3 A | 62.16 A | 41.44 A | 12.43 A | 6.487 A |
| 2.0107 HP | 1500 W | 125 A | 62.5 A | 41.66 A | 12.5 A | 6.521 A |
| 2.5 HP | 1865 W | 155.4 A | 77.71 A | 51.81 A | 15.41 A | 8.108 A |
| 2.68 HP | 2000 W | 166.6 A | 83.3 A | 55.5 A | 16.66 A | 8.695 A |
| 3 HP | 2238 W | 186.5 A | 93.25 A | 62.16 A | 18.65 A | 9.730 A |
| 4 HP | 2984 W | 248.6 A | 124.3 A | 82.88 A | 24.86 A | 12.97 A |
| 4.021 HP | 3000 W | 250 A | 125 A | 83.33 A | 25 A | 13.04 A |
| 5 HP | 3730 W | 310.8 A | 155.4 A | 103.6 A | 31.08 A | 16.21 A |
| 5.3619 HP | 4000 W | 333.3 A | 166.6 A | 111.1 A | 33.33 A | 17.39 A |
| 6 HP | 4476 W | 373 A | 186.5 A | 124.3 A | 37.3 A | 19.46 A |
| 6.70 HP | 5000 W | 416.6 A | 208.3 A | 138.8 A | 41.6 A | 21.74 A |
| 7.5 HP | 5595 W | 466.2 A | 233.1 A | 155.4 A | 46.6 A | 24.33 A |
| 10 HP | 7460 W | 621.6 A | 310.8 A | 207.2 A | 62.1 A | 32.43 A |
| 13.40 HP | 10000 W | 833.3 A | 416.6 A | 277.8 A | 83.3 A | 43.48 A |
| 26.80 HP | 20000 W | 1666.6 A | 833.3 A | 555.6 A | 166.6 A | 86.96 A |
So, if we check the table, 2000 watts converted to Amps is:
- @12V: 166.6 A,
- @24V: 83.3 A,
- @36V: 55.5 A,
- @120V: 16.66 A,
- @230V: 8.695 A.
As one can see, as the voltage is increased, the Amps decreases, for the same power transferred - this is the reason why, for example, 2000W power inverter's preferred input voltages are 24 or 36 or even 48V and not 12V.
In order to measure electric current, one can use ammeters in the form of digital multimeters, or clamp ammeters, depending on the current strength.
Long Story Short: If You want to calculate current in Amps from the power given in watts, You have to know the actual voltage and then use the following formula:
I(A) = P(W) / U(V)
And that is all ...
