1. What is an Amperage to Wattage Calculator?

Definition: This calculator converts electrical current (amperage) to power (wattage) using the voltage.

Purpose: It helps electricians, engineers, and DIYers determine the power consumption of electrical devices.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Power in watts
• \( I \) — Current in amperes (amps)
• \( V \) — Voltage in volts

Explanation: The current (amps) is multiplied by the voltage to calculate the power consumption in watts.

3. Importance of Wattage Calculation

Details: Proper wattage calculation ensures correct circuit sizing, prevents overloads, and helps estimate energy costs.

4. Using the Calculator

Tips: Enter the current in amps and voltage (default 120V for standard US household current). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between amps and watts?
A: Amps measure current flow, while watts measure power (rate of energy consumption).

Q2: What voltage should I use?
A: Standard household voltages are 120V (US) or 230V (Europe). Check your device specifications.

Q3: Can I calculate amps from watts?
A: Yes, by rearranging the formula: \( I = \frac{P}{V} \).

Q4: Does this work for DC and AC circuits?
A: For DC and purely resistive AC circuits. For reactive AC loads, power factor must be considered.

Q5: How does this relate to kWh?
A: kWh is watts multiplied by hours of use, then divided by 1000.
