You should not have to calculate the watts of the unit. All the information that you need will be on the nameplate of the unit. It is this information that electricians use to calculate the conductor size and breaker to supply the power to the unit.

Electrical power is also measured in Watts.
Watts = Volts x Amps x Power factor For an AC Unit I am guessing that your PF = .75 so we have 115 x 9.2 x .75 = 793.5 Watts.
Wattage is unit of power which is the product of Voltage in V and Current in Amps. If you know the current drawn by the appliance with 1200 Watts then you can calculate the Voltage = Power/ Current. For eg. if the current drawn by the appliance is 100A then the voltage is 1200/100 i.e. 12 Volts.
Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.
What size of central and heat unit do you need for 916 sq ft?
The idea here is to calculate 91% of 4000. By the way, technically "watts" is not a unit of energy. It is a unit of power - that is, energy per unit time.
There are NO watts in a millilitre. WATTS is a unit of power, Millilitre is a unit of VOLUME - there is no commonality.
You have to thaw it out.
watts
Watt is the unit of power. So in order to calculate power, both the voltage and current should be known.

volts is the unit of votage while watts is the unit of power
Central HVAC provides central air conditioning, central heating, and central ventilation packaged in one unit. As such it will heat, ventilate and cool your home.
my copper lines freezing on central air unit.
The typical power consumption of a heat pump system ranges from 3,500 to 5,000 watts, depending on the size and efficiency of the unit.
Installing a central air and heat unit in your home provides consistent and efficient temperature control, improved air quality, increased property value, and energy savings in the long run.
