Question

What is 240V in watts?

Answer 1

To convert **240 volts (V)** to **watts (W)**, you need more information because **volts alone are not enough** to determine the power (watts).

### Why? Because of this key formula:

$$
\text{Power (Watts)} = \text{Voltage (Volts)} \times \text{Current (Amps)}
$$

So:

$$
\text{Watts} = 240V \times \text{Current (in Amps)}
$$

### Therefore:

* If you know the **current (amperes)** being drawn by a device, you can multiply it by 240 volts to get the power in watts.

### Example 1: If current is 5 amps

$$
\text{Watts} = 240V \times 5A = 1200W
$$

### Example 2: If current is 10 amps

$$
\text{Watts} = 240V \times 10A = 2400W
$$

### Special Case: For resistive loads (like heaters or incandescent bulbs)

Sometimes you may also see formulas involving resistance:

$$
\text{Watts} = \frac{V^2}{R}
$$

Where:

* $V$ = voltage in volts (240V in your case)
* $R$ = resistance in ohms

But again, without knowing either **current (amps)** or **resistance (ohms)**, **you cannot calculate watts from volts alone**.

### Summary:

**240V is a measure of electrical pressure, not power.** To find watts, you must also know how much current is flowing (in amps) or the resistance (in ohms). Only then can you calculate how much power (in watts) is being used.

Would you like to calculate watts for a specific device or situation (like a heater, motor, or appliance)?
