The temperature scales we use have interesting stories behind them. Let’s take a look at the Celsius, Kelvin, and Fahrenheit scales!
The Celsius scale was created by a scientist named Anders Celsius in 1742.
He used the freezing and boiling points of water as his guide.
In this scale, 0 degrees Celsius (°C) is the freezing point of water, and 100 degrees Celsius is the boiling point at normal air pressure.
Pretty simple, right?
These reference points make it easy to understand everyday temperatures!
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724.
He decided that 32 degrees Fahrenheit (°F) is the freezing point of water, while 212 degrees Fahrenheit is the boiling point.
Fun fact: Fahrenheit used a few special reference points, including the coldest temperature he could make with a mix of salt and ice!
The Kelvin scale was invented by Lord Kelvin in 1848.
This scale is really important for science.
It starts at something called absolute zero, which is the point where all heat movement stops.
That’s a very cold -273.15 °C!
To find a temperature in Kelvin, you simply add 273.15 to the Celsius temperature.
This is super important for experiments where temperature can change how tiny particles behave.
All these scales help us understand and measure temperature in different situations!
