Unit Explanations
KilowattkW
Source UnitA kilowatt is a unit of power that is equivalent to 1,000 watts. It is widely used to measure the rate at which energy is used or generated. The kilowatt is part of the International System of Units (SI) and is often used for expressing the output power of engines and the power consumption of electric appliances. In the context of electrical power, one kilowatt is equal to the energy conversion or transfer of one thousand joules per second. It is a commonly used unit in many areas, including electrical engineering, physics, and everyday electricity billing.
Current Use
Today, kilowatts are used worldwide in numerous industries, including electricity generation, automotive, and manufacturing. It serves as a standard measurement for power output and consumption. Electric utilities use kilowatts to bill residential and commercial customers. The kilowatt also plays a crucial role in energy efficiency discussions as it allows for the comparison of the power consumption of various devices and systems.
Fun Fact
A single kilowatt can power ten 100-watt light bulbs.
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.

Definition
A kilowatt is a unit of power that is equivalent to 1,000 watts. It is widely used to measure the rate at which energy is used or generated. The kilowatt is part of the International System of Units (SI) and is often used for expressing the output power of engines and the power consumption of electric appliances. In the context of electrical power, one kilowatt is equal to the energy conversion or transfer of one thousand joules per second. It is a commonly used unit in many areas, including electrical engineering, physics, and everyday electricity billing.
History & Origin
The concept of the kilowatt emerged as technology evolved and the need for measuring power became more prevalent. The kilowatt was officially adopted as part of the International System of Units in 1960. It originates from the watt, named after James Watt, a Scottish inventor who made significant improvements to the steam engine in the 18th century. The kilowatt thus became a convenient way to express power on a larger scale, particularly as electrical power generation and consumption expanded.
Etymology: The term 'kilowatt' combines the prefix 'kilo-', meaning a thousand, with 'watt', the SI unit of power named after James Watt.

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.
