## How Many Amps Does A Microwave Use?

The microwave oven typically draws from 9 amps – 15 amps at 120 volts or about 5 amps to 9 amps at 220 volts depending on the input power rating.

You wonder that “How many amps does a microwave use on many different capacities”, you can refer to the information in the table below

##### Operating Voltage 120V (US)

Here we have taken the Input Power of the microwave (not the output power).

1100 W Input | 9.16 Amps |

1300 W Input | 10.83 Amps |

1500 W Input | 12.50 Amps |

1700 W Input | 14.16 Amps |

1850 W Input | 15.14 Amps |

##### Operating Voltage 220 (Europe, Asia)

At 220 volts, the current draw is lower. Why, because the higher the voltage, the lower is the current drawn.

1100 W Input | 5 Amps |

1300 W Input | 5.9 Amps |

1500 W Input | 6.81 Amps |

1700 W Input | 7.72 Amps |

1850 W Input | 8.4 Amps |

To find out how many amps your microwave uses, simply look at the wattage listed on the appliance.

The average microwave uses around 700 watts of power. Most microwaves have a maximum power output of 1000 watts.

To calculate the amps, simply divide the wattage by the voltage

**(1000 watts / 120 volts = 8.3 amps)**

This means that if you’re running your microwave on a standard 120-volt household circuit, it will draw 8.3 amps. If you’re running it on a 240-volt circuit (common in many kitchens), it will only draw 4.2 amps.

Of course, these are just averages – your specific microwave may use more or less power depending on its size and features.

For example, larger microwaves tend to use more power than smaller ones. And microwaves with additional features like convection cooking or sensor cooking will also use more power.

Keep in mind that this is just an estimate – the actual amp usage may be slightly higher or lower.

## How To Calculate The Amps Your Microwave Uses

Now that you know the average amps used by a microwave, let’s talk about how to calculate the amps used by your specific appliance.

Calculating the number of amps being used by a microwave is relatively simple. All you need to know is the wattage of the appliance and the voltage of the circuit.

Once you have this information, you can use the following formula to calculate the number of amps being used:

**Amps = Watts / Volts**

The first step is to find the wattage of your microwave. This should be listed on the appliance itself, either on the front panel or on a label on the back.

The easiest way to calculate the amps your microwave uses is to look at the wattage listed on the appliance.

Multiply the wattage by the number of hours you use the microwave each day. Then, divide that number by 1000. This will give you the number of kilowatts your microwave uses in a day.

For example, let’s say you have a 700-watt microwave that you use for 1 hour each day. You would multiply 700 watts by 1 hour, which equals 700 watt-hours. Divide that by 1000, and you get 0.7 kilowatts.

To convert kilowatts to amps, simply divide the number of kilowatts by the voltage of your circuit (usually 120 or 240).

For our example, we would divide 0.7 kilowatts by 120 volts, which equals 5.8 amps. This means that our 700-watt microwave would use about 5.8 amps on a standard 120-volt household circuit.

Of course, keep in mind that this is just an estimate – the actual amps used by your microwave may vary depending on the model, features, and size.

If you’re really concerned about saving energy and reducing your carbon footprint, there are some simple steps you can take to reduce the amount of power your microwave uses.

For instance, try microwaving food in smaller portions or using lower-wattage settings whenever possible.

You may also want to consider buying a newer, more energy-efficient model that uses less power overall. And finally, unplug your microwave when it’s not in use to save even more energy.
