How to Calculate Amps, Volts, and Watts

Why are Electrical Ratings Important?

Hooking up your foodservice equipment to the wrong voltage is the number one reason for equipment failing to operate as it should. If you connect your new equipment to the wrong power supply, it won’t work as efficiently and may even become damaged.

Considering the investment required to outfit your kitchen with commercial equipment, you’ll want to make sure the electrical requirements are met. Use our voltage calculator to accurately calculate amps, voltage, or wattage so you can avoid this common misstep.

What are Amps, Volts, and Watts?

Wondering what the difference between amps and volts is? Voltage, amperage, and wattage are all related. Read on if you’re interested in learning more about these electrical terms and how they work together.

Amps: Amperes, commonly known as amps, measure the flow of electricity as an electric current. Specifically, they measure the amount of electrons that flow past a certain point per second. A common analogy used to describe how amps work is a garden hose.  Amps can be compared to the volume of water flowing through the hose. The more gallons of water flowing through the hose per minute, the stronger the current. Or, as the number of electrons flowing past a certain point per second increases, so do the amps.

Volts: How do we make those amps flow? Voltage. In sticking with the garden hose analogy, voltage is similar to the water pressure in the hose. The pressure, or force, is what causes the water to flow. Volts are a measure of how much force each electron is under, which is called "potential.” Potential is what causes electricity to flow. The difference between volts and amps is that amps measure the volume of electrons flowing while volts measure the pressure causing them to flow.

Watts: Amps and volts combine to create watts, a measurement of the amount of energy being released. In the case of the garden hose, this would be the amount of water flowing. The higher the wattage, which we now know is the combination of electrical potential and flow, the more power and output we'll see. For example, the more wattage a microwave has to offer, the faster it will cook your food.
