 # Energy Conversion Converter

Energy is a vital component of all activity that occurs on Earth. Everything that we do involves the conversion, or transformation, of energy.

This valuable resource is at the center of the most critical systems we encounter in daily life.

Luckily, our energy calculator makes energy conversion simple enough that anyone can do it with just a few simple steps.

## Why use an energy converter?

An energy conversion calculator shows us the amount of equivalent energy when transferred to different sources.

It helps us to determine these calculations in a manner that is time efficient and a way that makes solving equations easy to do on the spot.

As you will soon see, the conversion ratios indicate a complex relationship between the varied forms of energy and their related conversion processes.

This is one of the reasons that many people prefer using an energy conversion calculator to perform these types of highly skilled equations.

Most of us would find conversion equations to be exceedingly difficult when left to our own devices.

But, with a conversion calculator, advanced conversion factors are made much simpler, and tend to be much more efficient than attempting the task on one's own accord.

## What is energy?

By definition, energy is the ability of a system to do work.

Because energy is measured by a system's ability, the measurement of energy has long alluded students, scientists, and mathematicians.

Energy can be neither created or destroyed, it can only be converted from one form to another. This is one of the basic laws of energy.

### Converting Energy

Energy conversion involves the measurement of hard-to-measure subjects. Then, it translates these measurements into other forms.

But because of its' complicated definition, determining its conversion factors can seem equally complicated.

## Why convert energy?

It is important to maintain the level of useful energy as much as possible. Otherwise, energy is wasted.

This isn't to say that it's destroyed but only means that it is not transferred in a way that is helpful.

When converting energy the goal should be to do so in a way that maintains its' usefulness. Meaning, no energy is wasted during the conversion process.

To do this you need to be able to calculate the units of the energy that you are spending, or converting, to equal the units of the type of energy that you are converting it into, or creating.

## What are the common units of energy?

When converting energy, the units of energy must be considered to solve relevant equations.

There are two major types of energy units: basic, or common, energy units and source-based energy units.

When discussing common or basic energy units, the standard measurements include the following:

### Joule

The joule is the basic energy unit of the metric system. It is defined using meters, kilograms, and seconds.

### Calorie

A calorie was first defined in terms of heating water.

The traditional definition of a calorie is measured by the amount of heat required to raise the temperature of 1 gram of water by 1 degree C.

### British Thermal Unit

This is the British system analog of a calorie and is included when converting one caloric measurement to another.

### Kilowatt-Hour (kWh)

A kilowatt-hour is a standard unit of electricity production and consumption

### Large Scale Units

It's common to use large-scale units based on the joule, Btu, and kWh when referencing national or global energy budgets.

## How do you convert energy units?

The following conversion ratios are used when solving equations for common large scale units:

### Exajoule (EJ) to Joule

1 EJ = 1018 J

1 quad = 1015 Btu = 1.055 EJ

### Terawatt-year (TWyr) to kWh to EJ to Quad

1 TWyr = 8.76 x 1012 kWh = 31.54 EJ = 29.89 quad

## What are the three principles of energy?

The three principles, or laws, of thermodynamics, emerged from the hard work of the 19th-century scientists.

Here are the three basic tenets that they came up with, which are still relevant today.

### 1. Energy can be neither created or destroyed.

The first basic law of energy states that we cannot create or destroy energy, which means that the amount of energy in the universe is at a constant level.

This is known as the law of conversion because energy is only converted from one form to another.

### 2. The entropy of an isolated system always increases

The second law states that when energy moves from one source to another, entropy always increases.

Entropy is basically a state of disorder.

### 3. The energy of a system approaches a constant value as the temperature approaches zero

The third law is the basis of why we should attempt to convert energy so that it remains in a useful form, rather than a form that is chaotic and harmful to the Earth's energy levels.
