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.
Kilovolt AmperekVA
Target UnitThe kilovolt ampere (kVA) is a unit of measurement that represents apparent power in an electrical system. It is defined as 1,000 volt-amperes (VA) and is used to quantify the total amount of power being used in an electrical circuit, irrespective of the phase angle. The unit takes into account both voltage and current but does not factor in the power factor, which distinguishes it from kilowatts (kW). It is particularly significant in AC (alternating current) systems, where the relationship between voltage and current can be complex. The formula for calculating kVA is kVA = Voltage (V) x Current (A) / 1000.
Current Use
Today, the kilovolt ampere is extensively utilized in the electrical industry for specifying the capacity of transformers, generators, and uninterruptible power supplies (UPS). It serves as a crucial indicator of the total load that electrical equipment can handle, enabling engineers and technicians to design and manage electrical systems effectively. In commercial buildings, kVA ratings help ensure that power supplies can meet the demands of various electrical systems, mitigating risks of overload and equipment failure.
Fun Fact
The kilovolt ampere is often confused with kilowatts; however, kVA does not account for the power factor.

power • Non-SI
Definition
The kilovolt ampere (kVA) is a unit of measurement that represents apparent power in an electrical system. It is defined as 1,000 volt-amperes (VA) and is used to quantify the total amount of power being used in an electrical circuit, irrespective of the phase angle. The unit takes into account both voltage and current but does not factor in the power factor, which distinguishes it from kilowatts (kW). It is particularly significant in AC (alternating current) systems, where the relationship between voltage and current can be complex. The formula for calculating kVA is kVA = Voltage (V) x Current (A) / 1000.
History & Origin
The concept of apparent power arose in the early 20th century as electrical systems became more complex with the widespread adoption of AC power. The kilovolt ampere designation was established to provide a standardized measurement for power that reflects both voltage and current without considering phase differences. This was especially essential during the expansion of electrical grids and systems, where accurate measurements of power were crucial for efficiency and safety.
Etymology: The term 'kilovolt' derives from the prefix 'kilo-' meaning one thousand, combined with 'volt,' a unit of electric potential. 'Ampere' is named after André-Marie Ampère, a French physicist who made significant contributions to electromagnetism.
