## Conversions Between Different Temperature Scales

There are three different scales of temperature measurement, which are:

Here are some equations for conversion from one scale to another.

[°C] = ([°F] − 32) × (5/9)

[°K] = [°C] + 273.15

Imagine two friends of you is going to visit you next week.

One of them is from Europe and the other is a scientist.

They would like to know how the weather is going to be like next week in Athens so that they could bring proper clothing with them. How would you interpret the weather report for them?

Temperature conversions are one-step equations. In order to be able to solve one-step equations you need three pieces of knowledge that you already have. These are:

- Fahrenheit scale [°F]: Developed by Daniel Gabriel Fahrenheit (1686–1736) mainly used by meteorologists for measuring surface temperature. Mainly used in the U.S..

- Celsius scale [°C]: This scale is developed by Swedish astronomer Anders Celsius (1701–1744) to measure surface temperature. Mainly Used in Europe.

- Kelvin scale [°K]: Developed by a physicist and engineer William Thomson, 1st Baron Kelvin (1824–1907). Kelvin scale starts at absolute zero, so it doesn't have negative temperatures. It is mainly used by scientists.

Temperature conversions are one-step equations. In order to be able to solve one-step equations you need three pieces of knowledge that you already have. These are:

- Identifying like terms.

For example: What are like terms in this expression? 2x + 5 + 3x - 7 - Finding reciprocal of a number or expression.

For example: What is the reciprocal of -2, 1/2, x. - Collecting like terms and simplifying expressions.

For example: Simplify 5x - (7 -2x)
