A kilojoule (kJ) is a unit used to measure energy.
Just like a kilometer is 1,000 meters, a kilojoule is 1,000 joules. Kilojoules are part of the International System of Units (SI), the modern form of the metric system.
They are used worldwide to measure energy in food, physics, and everyday life.
Key Takeaways:
In nutrition, kilojoules (kJ) are the international standard for measuring the energy we get from food and drinks.
You'll often see them listed alongside calories (cal) on nutrition labels, especially outside of the United States.
Understanding the relationship between them is easy. The conversion is simple: 1 calorie is about 4.2 kilojoules.
Knowing this helps you accurately track your energy intake and easily compare food products, no matter where you are in the world.
As a multiple of the joule, the kilojoule (kJ) is a fundamental unit for measuring work and energy in scientific fields like physics and chemistry.
One kilojoule (1,000 joules) is roughly the energy needed to lift a 100-kg (220-lb) object one meter off the ground.
This standardization allows scientists to make precise and consistent energy calculations in experiments and research.
Beyond food labels and science labs, kilojoules help quantify the energy we use for everyday activities and appliances.
Thinking in kilojoules offers a practical way to understand and manage your personal energy expenditure.

Have you ever heard terms like "gigawatt-hour" and wondered what they actually mean?
Understanding energy units like the Gigawatt-hour (GWh) is key to grasping the scale of power generation and power consumption in our modern world.
This article breaks down what a GWh is, how it compares to other units, and why it's so crucial for measuring renewable energy.
A Gigawatt-hour (GWh) is a unit used to measure a massive amount of energy.
To be precise, one GWh is equivalent to 3.6 trillion Joules ( J).
So, how much energy is a GWh? A single gigawatt-hour is enough to power about 100,000 homes for a full day or a major city like San Francisco for several hours.
This unit is commonly used to describe the energy consumption of large cities or the output of major power plants, providing a tangible scale for understanding national or regional electricity usage.
The gigawatt-hour is part of a clear system of energy measurement.
One Gigawatt-hour (GWh) is equivalent to 1,000 Megawatt-hours (MWh) or 1,000,000 Kilowatt-hours (kWh).
While your monthly electricity bill is measured in the much smaller kilowatt-hour (kWh), utility-scale projects are measured in GWh. This highlights the vast difference between your home's energy use and the amount of power generated for an entire community.
Gigawatt-hours are a critical metric for tracking the output of large-scale renewable energy facilities, such as wind farms, solar arrays, and hydroelectric dams.
For example, a large offshore wind farm's annual energy production is often stated in GWh.
This allows for a direct comparison of its capacity to contribute to the power grid and displace fossil fuels.
