An energy converter is a device or system that changes energy from one form to another. For example, a battery is an energy converter that converts chemical energy into electrical energy, while a generator converts mechanical energy into electrical energy. Another example is a heat engine which converts thermal energy into mechanical energy. Energy converters are used in a variety of applications, including power generation, transportation, heating and cooling, and many others. The efficiency of an energy converter determines the amount of usable output energy relative to the input energy.

An energy converter is a device or system that changes one form of energy into another. Some common types of energy converters include:

- Thermal energy converters (e.g. boilers, furnaces)
- Electrical energy converters (e.g. batteries, generators)
- Mechanical energy converters (e.g. engines, turbines)
- Solar energy converters (e.g. photovoltaic cells, concentrated solar power)
- Wind energy converters (e.g. wind turbines)

The efficiency of an energy converter determines the proportion of input energy that is converted into useful output energy.

**What does an energy converter do?**

An energy converter changes one form of energy into another. It takes in energy in one form (such as electrical, mechanical, or thermal energy) and converts it into a different form that can be more easily used or stored. Energy converters play an important role in many industries, including power generation, transportation, and manufacturing.

**How do you calculate energy conversion?**

Energy conversion can be calculated using the formula:

Output Energy = Input Energy x Conversion Efficiency

The conversion efficiency is a measure of how much of the input energy is converted into usable output energy and is expressed as a fraction or percentage. For example, if a device has a conversion efficiency of 50%, this means that 50% of the input energy is converted into usable output energy, while the remaining 50% is lost as waste heat or other forms of energy.

To calculate the output energy, simply multiply the input energy by the conversion efficiency. For example, if the input energy is 100 units and the conversion efficiency is 50%, then the output energy would be 100 x 0.5 = 50 units.

**Energy Unit Conversion Table**

Here is a table of some common energy unit conversions:

1 Joule (J) =

- 0.000277778 watt-hours (Wh)
- 0.2388 calories (cal)
- 0.7375 foot-pounds (ft-lb)

1 Kilowatt-hour (kWh) =

- 3.6 million joules (MJ)
- 3412 British thermal units (BTU)
- 860,420 calories (cal)

1 BTU (British Thermal Unit) =
