What is the Formula to convert Watt-hour to Megajoules?
The formula to convert given energy from Watt-hour to Megajoules is:
Energy(Megajoules) = Energy(Watt-hour) × 3.6e-3
Substitute the given value of energy in watt-hour, i.e., Energy(Watt-hour) in the above formula and simplify the right-hand side value. The resulting value is the energy in megajoules, i.e., Energy(Megajoules).
Calculation
Calculation will be done after you enter a valid input.
Examples
1
Consider that we have a light bulb that consumes 300 watt-hours (Wh) of energy over the 5 hours it was on. Convert this energy consumption from watt-hours to Megajoules.
Answer:
Given:
The energy in watt-hour is:
Energy(Watt-hour) = 300
Formula:
The formula to convert energy from watt-hour to megajoules is:
Energy(Megajoules) = Energy(Watt-hour) × 3.6e-3
Substitution:
Substitute given weight Energy(Watt-hour) = 300 in the above formula.
Energy(Megajoules) = 300 × 3.6e-3
Energy(Megajoules) = 1.08
Final Answer:
Therefore, 300 Wh is equal to 1.08 MJ.
The energy is 1.08 MJ, in megajoules.
2
Consider that a rechargeable battery stores 500 watt-hours (Wh) of energy. Convert this stored energy from watt-hours to Megajoules.
Answer:
Given:
The energy in watt-hour is:
Energy(Watt-hour) = 500
Formula:
The formula to convert energy from watt-hour to megajoules is:
Energy(Megajoules) = Energy(Watt-hour) × 3.6e-3
Substitution:
Substitute given weight Energy(Watt-hour) = 500 in the above formula.
Energy(Megajoules) = 500 × 3.6e-3
Energy(Megajoules) = 1.8
Final Answer:
Therefore, 500 Wh is equal to 1.8 MJ.
The energy is 1.8 MJ, in megajoules.

Watt-hour
A Watt-hour (Wh) is a unit of energy that measures the amount of electrical energy consumed or generated over time. One Watt-hour is equivalent to one watt of power used or produced for one hour. This unit is commonly used to quantify energy usage in households, industries, and various devices. For instance, a 100-watt light bulb running for 10 hours consumes 1000 watt-hours, or 1 kilowatt-hour (kWh). Watt-hours are essential for understanding energy consumption, billing in electric utilities, and managing energy efficiency.
Megajoules
A Megajoule (MJ) is a unit of energy equal to 1,000,000 joules. It is commonly used to measure large quantities of energy in various scientific, engineering, and industrial contexts. One megajoule represents the amount of energy required to apply a force of one newton over a distance of one million meters, or the energy transferred when one megawatt of power is applied for one second. Megajoules are often used to quantify the energy content of fuels, the work done by large machines, and the energy used or produced in industrial processes, providing a standard measure for comparing significant energy transfers and consumption.
Frequently Asked Questions (FAQs)
1. What is the formula for converting Watt-hour to Megajoules in Energy?
