![]() ![]() There will be losses within the UPS and power distribution system. There are some additional sources of heat that should also be considered. The conversion is not 100%, but it is close enough to assume each kWh of energy consumed produces one kWh of heat in the rack. Almost all the energy provided to a server is converted to heat. Understanding the energy consumed is important since this will approximate the heat produced. For example, a rack that requires 2.5 kW of power will consume 2.5kWh of energy during one hour. When talking about electrical energy, the most common term is kiloWattHours (kWh). The next step is to discuss energy.Įlectrical energy is work done (power consumed) over time. Either way, this is an expression of power. Fans, motors, transformers and other equipment have lower power factors and which will result in significant differences.) So, kVA can also be expressed in watts. For electronics the power factor is nearly one, meaning the two numbers will be almost equal. (The actual difference is determined by the power factor of the load. However, for IT equipment, the approximation of 1 watt being equal to 1 VA is close enough for discussion. What about watts? Watts is another measure of power and is often used interchangeably with VA. Most often, this is reported in kiloVoltAmps (kVA). The actual power provided by the UPS or PDU is usually available from the display panel or other interface. A better-and often easier-approach is to measure the output power at the UPS or PDU. Actual consumption is usually much less, especially when averaged across all devices. However, keep in mind the nameplate is required to list the maximum possible consumption (so wiring and circuit breakers can be properly planned). You could count up and sum the power requirements for all the IT equipment. ![]() On each piece of IT equipment (or in the manual) there will be a specified power requirement. What is the electrical load of your data center? The equipment nameplate is one possible place to start. And, when compared apples-to-apples the results can be surprising. Fortunately, there are a few simple tricks to quickly compare the power and cooling capacities within the data center. When that happens, the results can be serious: from dollars lost through inefficiency to unexpected constraints on growth. So, while power and cooling are related, sometimes something gets lost in translation. When discussing cooling we usually talk in terms of tons and BTUs. For electrical systems, we use terms like volts, amps, KVA and watts. The challenge: power and cooling each have their own language. Yet, it is often difficult to directly compare the two. Of course, the power supplied and the heat removed are closely related: in their simplest form, both are just measures of energy. When it comes to data center design, operation and optimization, it is all about power and cooling. You can also get the formula used in Watt to Btu (IT) per Hour conversion along with a table representing the entire conversion.Tons of electrical energy, Watts of cooling? If you encounter any issues to convert, this tool is the answer that gives you the exact conversion of units. Converting Watt to Btu (IT) per Hour is easy, for you only have to select the units first and the value you want to convert. When you are converting power, you need a Watts to Btu (IT) per Hours converter that is elaborate and still easy to use. helps in the conversion of different units of measurement like W to Btu/h through multiplicative conversion factors. Be it buying grocery or cooking, units play a vital role in our daily life and hence their conversions. Measurement like power finds its use in a number of places right from education to industrial usage. 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.
