Farenheit degrees converter

The Celsius and Kelvin scales are precisely related, with a one-degree change in Celsius being equal to a one degree-change in kelvin. The kelvin and thus Celsius is defined based on the Boltzmann constant, k, which equals 1. Celsius as a unit and a scale was not widely used until this original definition was inverted.

In , the unit, "degree Celsius," as well as the Celsius scale were again re-defined to instead be based on absolute zero This is the definition that was used up until , when the kelvin was redefined based on the definitions of the second, meter, and kilogram. Most things we measure — length, width, time etc.

We all know exactly how long zero centimeters or inches is, and can convert zero of any of those units into another type of unit very easily. Taking inches and centimeters as an example, to go from zero inches to 1 inch we need to add one inch. So far, so obvious. Similarly, to go from zero centimeters to 1 centimeter, we need only add 1 centimeter. The only difference between adding one inch or one centimetre is the amount of distance we're adding. The relationship between an inch and a centimetre is that 1 inch is 2.

So we can say that adding 1 inch is the same as adding 2. Temperature units aren't built in the same simple way, because they don't all start in the same place at zero. You might have heard about the temperature. You have also heard that the outside temperature is very cold tonight or something like that.

You also need to know the temperature of our body when we have a fever. How are all these measurements possible? Obviously we need some device to measure the temperature.

This device is known as a thermometer.
