### Temperature conversion rates

Fahrenheit = 1.8 * (Celsius) + 32

Kelvin = Celsius + 273.15

Fahrenheit = 1.8 *(Kelvin – 273.15) + 32

### Temperature info

The amount of heat energy present in a substance is the physical property of temperature. Of the three major temperature scales, the Kelvin is the SI unit of temperature. This is due to the fact that 0 Kelvin is equivalent to absolute zero, the lowest possible energy state. The name comes from the scientist who devised the scale, Lord Kelvin.

Whereas the kelvin is used in scientific situations, the celsius the most widely used scale. The scale moves at the same rate as the kelvin; that is to say that the gap between the freezing and the boiling point of water is 100 units in both scales. However, with celsius, 0 exists at the freezing point of water, which is 273.15 Kelvin. And so it follows that absolute zero is -273.15 celsius.

The final of the three units is the fahrenheit, which is the primary unit of the United States, along with a few other limited places. The definition of 0 fahrenheit is supposedly the freezing point of an equal part ammonium chloride – water solution. Furthermore, the freezing point of water is 32 fahrenheit and the boiling point can be found at 212. This makes a 1 degree change in celsius or kelvin equivalent to a 1.8 fahrenheit shift. Hence, the intersection between all three of these scales can be found at -40 degrees.

All measurements are assumed to have been taken at sea level, where standard atmospheric pressure exists.
