In , the "international" definitions were defined, with Siemens' definition being adopted as the international watt. These were used until when the General Conference on Weights and Measures re-defined the watt to absolute units, using only mass, time, and length. The absolute watt was adopted as the SI unit of power in Watt — A watt is rate measurement illustrating the rate of energy, a unit of power equivalent to 1 joule per second.
The watt was adopted because people needed a practical way to measure electrical power. James Watt — James Watt is the Scottish inventor after whom they named the watt after. Note that he did not discover the watt. Instead, scientists did this to honor him. He did greatly improve the steam engine and develop the concept of horsepower. Kilowatt — A kilowatt is watts and equals 1. To put this in practical terms, a square meter of Earth close to the Equator will receive on kilowatt of sunlight on a clear day at noon.
Horsepower — Horsepower HP is the abbreviation is a way to measure the rate at which work is done. One horsepower is what a good horse can pull, or the power that will lift pounds of weight by one foot in one second. One HP is There is a SI horsepower as well, at This measure made sense when steam engines were directly competing against pulling horses.
One watt second is a joule A light bulb will measure its energy in watt hours. A power plant will measure its energy in megawatt hours or gigawatt hours. Ampere — An ampere measures the current or flow of electricity. Scientists measure it in relation to the energy a single proton in an atom puts off. Volt — Voltage measures the flow of electricity between two points. Your electric socket in North America is volts. The third line on the electric train track is volts. One BTU is equal to the heat that will raise one pound of water by one degree Fahrenheit at sea level.
To give some conversions, one watt is about 3. Unit converter — Above you can see a wide range of units that measure the same or slightly different things. Different industries measure power in different ways. To bring two measures of energy together — like a heating fireplace and an electrical plug — someone needs to convert one unit to be the same as the other.
Unit converters are programs where if you put in one unit horsepower and get out another watts. Often people use conversion table or a conversion calculator for this task. Hour conversion calculator — An hour conversion calculator is used to turn hours and minutes 10 hours and 17 minutes back and forth to metric time We need this because many of the measurements require SI hours. We also talk about hour conversions when we measure rates. This single number contains explanations of two things at the same time.
Power converter — A power converters are calculators that lets you switch back and forth between units of energy. These units include watts, kilowatts, BTUs, and horsepower. These power conversions make it possible to communicate where people are using different units of power. Using this makes power conversion possible. A power converter is also a machine that turns AC alternating current into DC direct current and vice versa.
You need to find a number to start with — and BTU is a good place to start. If your energy is measured in watts, you will have to convert watts to BTU. The easiest way is to start with an online conversion calculator to take watts to BTU.
This BTU per hour conversion allows you to move from discussing energy to discussing heat. If you want to do it yourself, multiply your watts by 3. But the online converter makes the watts to BTU job easier. Then, you calculate the amount of BTUs you need to heat the spot that you desire to heat. You need enough BTUs or your heater will strain and cause cold spots.
Or you can use the fireplace as supplemental heating with an existing heating system also warming the room. You should find which heating zone you live in on a map. Different heating zone need different amounts of energy to heat a home. Here is an approximation for the US:. This number would be adjusted to reflect the amount of insulation and solar exposure you get.
That means your heating capacity generally furnace plus fireplace needs to equal , BTU. To use it wisely, you would need 95, from your furnace. Whether you have an architect and home builder plan one in, or if you plan yourself for a blank space on the wall and an electrical outlet, a fireplace can fit to provide both atmosphere and warmth. Your energy consumption matters.
You pay directly in your electricity and gas bills for the energy you consume. Much of our energy comes from dirty sources that release carbon dioxide when burned. This carbon dioxide is one of the main chemicals that lead to climate change. This phenomenon is not only warming but is leading to islands going underwater, farms getting little rain, and people being pushed off their land.
We need to lessen our energy consumption or get it from greener sources in order to fight climate change. A MagikFlame electric fireplace is an incredibly efficient form of energy.
Calculations for room volumes to determine the BTU requirement are typically done in feet, so tends to suit anyone who feels more comfortable using imperial measurements. The metric counterpart to BTUs is the calorie, which is the amount of energy needed to raise one gram of water by one degree Celsius at a pressure of one atmosphere. Watts are a unit of power representing an energy transfer of one joule per second and is part of the International System of Units.
As watts are a set global standard, their use within the UK predominates, although it tends to be more closely associated with electrical products for obvious reasons. Watts can sometimes be easier to understand when choosing an electric radiator size, as you can easily use their specified wattage to calculate their running cost using the pence per kWh provided by your energy supplier.
The electric radiators we offer at Heatingpoint have their heat output displayed in watts. You can use either measurement to work out whether an electric radiator will have enough power to heat your room. However, you should be aware that this is not an exact science, and you may find yourself getting into difficulties if you try to use these rules of thumb to choose other, less efficient heating solutions.
