Watt is a SI unit of power equivalent to J/s (joule per second). a unit of power equal to 1 joule per second; the power dissipated by a current of 1 ampere flowing across a resistance of 1 ohm. electronvolt . It may not display this or other websites correctly. For faster calculations, you can simply use our W to J/s . Joule noun. Answer link watt second (Ws) energy equivalent units. the SI unit of power, equivalent to one joule per second, corresponding to the rate of consumption of energy in an electric circuit where the potential difference is one volt and the current one ampere. Power is defined as the rate at which work is performed, or energy is converted. To other units. Energy is expressed in Joules, while power is expressed in Watts. Units of measurement use the International System of Units, better known as SI units, which provide a standard for measuring the physical properties of matter. CONVERT : between other power measuring units - complete list. Mathematically, P = W T [ w h e r e P = p o w e r, W = W o r k d o n e, t = t i m e t a k e n ] The SI units of work and time are Joules and seconds, respectively. Enter the power in watts, time in seconds and press the Calculate button: Joules to watts calculator Watts to joules calculation The energy E in joules (J) is equal to the power P in watts (W), times the time period t in seconds (s): E(J) = P(W) t(s) See also How to convert watts to joules Joules to watts calculator Watt Electrical calculation Be it buying grocery or cooking, units play a vital role in our daily life; and hence their conversions. 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 kgm 2 s 3. When talking about devices and appliances, using watt hours is a way of conveying how much electricity they use. Power consumption of small devices is typically measured in watts, while power consumption of larger devices is measured in kilowatts (kW). We assume you are converting between megawatt and erg/second. The formula used in watt-seconds to per meters conversion is 1 Watt-Second = 5.034117012218E+24 Per Meter. Use this page to learn how to convert between dyne centimeters/second and newton meters/second. h), 0.1 kilowatt hour, or 360 kJ. Watt A joule per second (J/s) is a a. Watt. One watt equals one joule per second, and one Wh = the amount of time it takes to produce an electrical current equivalent to 1000 watts. An equivalent is the power dissipated in an electrical conductor carrying one ampere current between points at one volt potential difference. The unit symbol for watt is W, defined as one joule per second, measures the rate of energy conversion or transfer.
