# How to calculate amps

## What is the formula to calculate amps?

The formula for Amps is

**Watts divided by Volts**. To use the chart, cover up the A with your finger and use the remaining chart calculation of W divided by V. Using our sample panel data, 60 watts divided by 12 volts equals 5 amps.## How do I calculate amps from watts?

Converting watts to amps can be done using the power formula, which states that

**I = P ÷ E**, where P is power measured in watts, I is current measured in amps, and E is voltage measured in volts. Thus, the current I in amps is equal to the power P in watts divided by the voltage V in volts.## How do you calculate amps from volts?

**Amps = Watts / Volts**

- 4160 Watts / 208 Volts = 20 Amps.
- 3600 Watts / 240 Volts = 15 Amps.

## How do I calculate current?

The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as

**I = V/R**. The SI unit of current is Ampere (Amp).## What is current formula?

Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is

**I = V/R.**## What is 30 amps in watts?
