This page will explain in simple terms the difference between the power ratings and describe when each should be used in your data center and network architecture planning. A KVA is simply 1,000 volt amps. A volt is electrical pressure. An amp is electrical current. A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps. On the other hand, a watt (W) is a measurement of real power. Real power is the amount of actual power that can be drawn from a circuit. When the voltage and current of a circuit coincide, the real power is equal to the apparent power.

However, as waves of current and voltage coincide less, less real power is transferred, even though the circuit is still carrying current. Differences between real and apparent power, and thus watts and volt amps, arise because of inefficiencies in electrical transmission. The resulting inefficiency of electrical transmission can be measured and expressed as a ratio called the power factor. The power factor is a ratio (a number from 0 to 1) of real power and apparent power. In the case of a 1.0 power factor, the real power equals the apparent power. In the case of a 0.5 power factor, real power is approximately half that of the apparent power. Deploying systems that have higher power factors result in less electrical loss and can help improve your Power Usage Effectiveness (PUE). Most Universal Power Supply (UPS) units will list the average power factor and real-time load capacity of the UPS, in addition to the KVA. Example: You own a 500 KVA UPS unit (apparent power) with a 0.9 power factor. 

The resulting real power is 450 kilowatts. Some Useful Conversion Factors and FormulasBy far the most common question we get from customers who are considering installing Central Air Conditioning is what it will cost to operate it in the Edmonton Area. The formula for calculating the exact cost can be fairly intimidating but the following Laymans rule of thumb will provide you a budgetary amount that will only be slightly higher or slightly lower once the bills start coming in. Determine the Amperage of your unit.  For a 13 SEER unit which is the most common in Edmonton  a 2 ton unit is typically 17 amps, a 3 ton unit 19 amps and a 4 ton unit 21 amps Calculate the wattage used by your unit. All Central Air Units are wired to run on 240 volts so to calculate your wattage multiply the amps by 240.  for a two ton unit it would be 17 x 240 = 4080 watts Electricity is billed by KWh, to determine the KWh for the size of your unit divide the wattage used by 1000. In this case  4080 / 1000 = 4.08 KWH

Multiply your cost per KWH, approximately 12.7 cents in the Edmonton area by your KWH. In the case of this 2 ton unit  12.7 x 4.08 =  51.81 cents per hour would be your approximate cost of operation. If your unit ran for 24 hours a day the cost to operate it would be $12.43 per day or 375.00 per month. A properly sized air conditioner does not run 24 hours a day, not even in 40 degree heat without any drop in temperature at night. As a general rule and assuming you set your thermostat to Cool to 21 degrees Celsius you can determine how many hours your unit will run during the day by using the following factors: Multiply your 24 hours cost per month by the above factors to determine your approximate monthly cost based on weather patterns in Edmonton. In this case, the two ton unit operating with average outdoor temperatures of 26 degrees would  be $375.00 x .25 = $93.75 per month.
