# Why is 40 degrees Celsius 40 degrees Fahrenheit?

**40**°

**C**and -

**40**°

**F**are actually the SAME! That means that from the mark of -

**40**, for each degree that the

**Fahrenheit**scale goes up or down, the

**Celsius**scale only moves 5/9 of a degree. That's why the freezing point of water is 0°

**C**but 32°

**F**, and the boiling point of water is is100 0°

**C**but 212°

**F**!

Also know, is 40 degrees Fahrenheit the same as 40 degrees Celsius?

The **Fahrenheit** and **Celsius** scales have one point at which they intersect. They are equal at -**40** °**C** and -**40** °**F**. The simple method to find when two temperature scales are equal to each other is to set the conversion factors for the two scales equal to each other and solve for temperature.

Celsius | Fahrenheit |
---|---|

20°C | 68°F |

30°C | 86°F |

40°C | 104°F |

50°C | 122°F |

Likewise, why do Celsius and Fahrenheit meet 40?

To find the temperature when both are **equal**, we use an old algebra trick and just set ºF = ºC and solve one of the equations. So the temperature when both the **Celsius and Fahrenheit** scales are the same is -**40** degrees.

Water Temperature The more dots on the tag, the hotter the water should be—one dot represents **cold**, or 30 **degrees Celsius**; two dots for warm, or **40 degrees**; three dots for **hot**, or 50 **degrees**; and four dots for extra **hot**, or 60 **degrees**.
