![]() In relation to the base unit of => (amperes), 1 Watts Per Volts (W/V) is equal to 1 amperes, while 1 Milliamperes (mA) = 0.001 amperes. How to convert Watts Per Volts to Milliamperes (W/V to mA)?Īlways check the results rounding errors may occur. The base unit for electric current is amperes (SI Unit) Conversion: Watts Per Volts to Milliamperes Learn more about how to design and build a data center. ![]() ![]() Power supplies and energy use are important parts of designing a data center. Kilowatt-hour is an important metric for measuring performance of high-capacity power systems, such as uninterruptible power systems and diesel generators. Dividing the number of watt-hours by 1,000 results in the equivalent kilowatt-hours as shown in the following equation: What about kilowatt hours (kWh)?Ī kilowatt-hour is another important energy metric that assumes the generation of 1,000 watts for one hour. If the car travels at 60 mph for one hour, it travels 60 miles in distance. That's analogous to watts, in that the car's speed at any moment is 60 mph. For example, an automobile may run at 60 miles per hour. Speed and distance are also useful analogies to wattage and watt-hours. Watts describe the level of power at a moment in time, whereas watt-hours describe the amount of power consumption over a period of time. This information is also useful for determining if a device would benefit from being replaced with a more energy efficient version that will help users cut energy consumption and electricity bills and increase energy efficiency. Knowing the potential electrical power use of a device also provides insight into when it might need to be replaced. Watt-hours can be used to determine the energy usage of various electrical devices, such as standard light bulbs, over time. Watt-hours are also used as a measure of how much energy a solar panel can produce. Watt-hours are used to measure battery capacity and battery life, estimate number of times the battery can recharge a device and provide a metric for comparing battery performance. kWh to watts calculator Watts to kWh calculation. With a battery that displays its ratings as 10 amp hours (Ah) operating at 12 volts, multiplying the battery voltage by the amp hour rating provides the watt-hours of the battery as shown in the following equation: Watt-hours are useful in a different way. Watts Bar Unit 2 is TVAs seventh operating nuclear reactor delivering carbon-free energy to the Tennessee Valley, helping to generate enough clean. BTU (British Thermal Unit) is a unit of heat. Watts represent the amount of energy flowing in a circuit and are computed using this formula: In many countries, electric bills are based on. 1000 watts is called a kilowatt, written as kW. An equation for solving Power, Work and Time is Power Work Time, Work Power × Time, or Time Work Power. Watt-hours help people understand the amount of power available in various items, such as batteries. Watt is a unit of power, joule is a unit of work and energy, and time is a unit of time. 100 Amps To Watts (Example 3) More powerful electrical units can draw as much as 100 amps. Voltage and current, which is measured in amperes, play key roles in calculating watt-hours. If the voltage would be 220V, 15 amps would equal to 3300 W. If a unit of power and time are not specified in watts and number of hours, respectively, then they must be converted to those units before determining energy in watt-hours. Then P = 60 and t = 3, so the total energy E in watt-hours is: Suppose a 60 watt light bulb burns for 3 hours. To determine energy in watt-hours, power must be expressed in watts, and time must be expressed in hours. How are energy and watt-hours related?Įnergy (E) is equivalent to power (P) multiplied by time (t). If this energy is used to operate an electricity generator, the output of the generator over a period of time can be expressed in watt-hours. The heat energy resulting from combustion of such fuels is usually expressed in joules according to the International System of Units or in British thermal units according to the foot-pound-second or English system. ![]() Home Volts To Watts Volts to Watts Converter. It helps you to convert units from volts to watts or vice versa & find how many watts in a volt with a formula. A quantity of gasoline, oil or coal contains potential energy that is liberated when the fuel is burned. Volts to watts is a volts to watts converter. The watt-hour is most often used to express electrical energy in any form. To obtain watt-hours when joules are known, multiply the number of joules by 2.778 x 10 -4. To obtain joules when the watt-hours are known, multiply the number of watt-hours by 3.600 x 10 3. The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications.Īn energy expenditure of 1 Wh represents 3,600 joules or 3.600 x 10 3 J. The watt-hour, which is symbolized Wh, is a unit of energy equivalent to one watt of power expended for one hour of time.
