- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the zettajoule value by 3.6e-21. This alternative method also gives you the correct energy in milliwatt-hours.
- Illustration of Division:
- Milliwatt-hour = zj ÷ 3.6e-21
What is Energy?
Energy is the capacity of a physical system to do work or produce heat. The SI unit is the joule (J), defined as the work done when a force of one newton is applied over one meter (1 J = 1 N·m = 1 kg·m²/s²). Other important units include the kilowatt-hour (kWh)—used on electricity bills (1 kWh = 3.6 MJ)—the calorie (cal)—used in nutrition (1 food Calorie = 1 kcal = 4,184 J)—and the electronvolt (eV), used in atomic and particle physics (1 eV = 1.602 × 10⁻¹⁹ J).
What is Zettajoule?
Zettajoule (symbol: ZJ) is a metric unit of energy equal to 1021 joules. It is commonly used to describe global energy consumption, climate studies, ocean heat content, and other large-scale scientific measurements. Learn more about zettajoule.
What is Milliwatt-hour?
A milliwatt-hour (mWh) is a unit of electrical energy equal to one thousandth of a watt-hour, or the amount of energy a one-milliwatt device consumes in one hour. The milliwatt-hour is standard for specifying battery capacity in portable electronics including smartphones, smartwatches, wireless earbuds, and portable power banks. Medical devices like pacemakers and implanted sensors also specify energy in milliwatt-hours. The unit produces practical numbers for low-capacity devices—most smartphone batteries range from 2,500 to 5,000 mWh, numbers that are easier to communicate and compare than 2.5-5.0 Wh.
