In direct current (DC) circuits, this product is equal to the real power, measured in watts. [3] The volt-ampere is dimensionally equivalent to the watt: in SI units, 1 V⋅A = 1 W. VA rating is most used for generators and transformers, and other power handling equipment, where loads may be reactive (inductive or capacitive).
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m 2 ⋅s −3. [1] [2] [3] It is used to quantify the rate of energy transfer.

Airwatt or air watt is a unit of measurement that represents the true suction power of vacuum cleaners. It is calculated by multiplying the airflow (in cubic metres per second ) by the suction pressure (in pascals ).
As of April 2010, WBIS, along with WAGE in Leesburg, Virginia, effectively had the same ownership. On October 29, 2008, the Leesburg station received permission from the Federal Communications Commission (FCC) to move from 1200 to 1190 kHz and raise its power to 50 kW. On April 21, 2010, the FCC approved applications for WAGE to increase its ...
WTSD (1190 kHz) is a commercial AM radio station licensed to Leesburg, Virginia, and serving the Washington metropolitan area with a sports radio format. [4] Owned by Potomac Radio Group, Inc., the station has been operated by iHeartMedia since January 2023, as part of that broadcast chain's cluster of stations. [5]
Mexico, for example, typically runs 150,000 to 500,000 watts, but some stations are grandfathered at 10,000 to 20,000 watts at night; by treaty, these sub-50,000 watt Mexican stations may operate with a maximum of 100,000 watts during the daytime. [3]
A ton of refrigeration (TR or TOR), also called a refrigeration ton (RT), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.
