Unit Explanations
WattW
Source UnitThe watt (symbol: W) is the SI unit of power, defined as the rate of energy transfer equivalent to one joule per second. It measures the amount of energy conversion or transfer that occurs per unit time. In practical terms, it quantifies the rate at which work is done or energy is consumed. The watt is a derived unit in the International System of Units (SI), and it is used extensively in various fields such as electricity, mechanics, and thermodynamics to quantify power output or consumption.
Current Use
The watt is widely used across the globe to measure electrical power, mechanical power, and heat transfer. It serves as a fundamental unit in the fields of electrical engineering, physics, and many applied sciences. It is crucial for calculating energy consumption in households, industries, and for determining the power output of engines and machinery.
Fun Fact
One watt is equivalent to 1/746th of a horsepower.
Petajoule SecondPJ·s
Target UnitThe petajoule second (PJ·s) is a derived unit of power that quantifies energy transfer in the amount of one petajoule occurring over one second. It is a measure of work done or energy used per unit time, where one petajoule equals 10^15 joules. This unit is particularly useful in contexts where large-scale energy transfers, such as those involving fossil fuels or renewable energy sources, are analyzed. The relationship between energy and time allows for an understanding of the efficiency and intensity of energy production and consumption.
Current Use
The petajoule second is primarily used in fields that require the measurement of large amounts of energy over time, such as nuclear physics, renewable energy studies, and large-scale engineering projects. It allows for easier comparisons and calculations when dealing with energy needs and outputs in terms of power generation and consumption.
Fun Fact
A petajoule is equivalent to the energy released by burning approximately 24,000 gallons of gasoline.

Petajoule Second
power • Non-SI
Definition
The petajoule second (PJ·s) is a derived unit of power that quantifies energy transfer in the amount of one petajoule occurring over one second. It is a measure of work done or energy used per unit time, where one petajoule equals 10^15 joules. This unit is particularly useful in contexts where large-scale energy transfers, such as those involving fossil fuels or renewable energy sources, are analyzed. The relationship between energy and time allows for an understanding of the efficiency and intensity of energy production and consumption.
History & Origin
The concept of the joule as a unit of energy was named after the English physicist James Prescott Joule in the mid-19th century. The petajoule, being a multiple of the joule, emerged with the need to quantify large energy outputs in the modern age, particularly during the rise of electricity and nuclear power.
Etymology: The term 'petajoule' is derived from the prefix 'peta-' which signifies a factor of 10^15, combined with 'joule' from James Prescott Joule's surname, reflecting the unit's association with energy.
Current Use
The petajoule second is primarily used in fields that require the measurement of large amounts of energy over time, such as nuclear physics, renewable energy studies, and large-scale engineering projects. It allows for easier comparisons and calculations when dealing with energy needs and outputs in terms of power generation and consumption.
💡 Fun Facts
- •A petajoule is equivalent to the energy released by burning approximately 24,000 gallons of gasoline.
- •Petajoule measures can also indicate the energy content of various food sources, with 1 PJ being enough to sustain several million people for a day.
- •The world's total energy consumption is measured in exajoules, where 1 exajoule equals 1,000 petajoules.
