Power Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans

What Is a Power Calculator?

A power calculator is a tool used to calculate the amount of power consumed or generated in a given system. In South Africa, this calculator is useful for individuals and businesses to estimate their electricity usage, determine the size of generators needed, or even assess the power output of renewable energy sources like solar panels. For example, homeowners can use a power calculator to budget for their monthly electricity bills based on their appliances’ power ratings.

How to Calculate Power Manually

The formula to calculate power is: Power (P) = Current (I) x Voltage (V). In South Africa, voltage is typically 230V for household electrical systems. For example, if a device draws 5 amps of current, the power consumption would be 1150 watts (P = 5A x 230V).

Let’s consider a scenario in South Africa where a refrigerator draws 3.5 amps of current at 230V. The power consumption of the refrigerator would be 805 watts (P = 3.5A x 230V).
