## Temperature Conversion: Celsius to Fahrenheit, Vice Versa

There are 2 main temperature scales:

Scale | Detail |

°C | the Celsius Scale (part of the Metric System, used in most other countries) |

°F | the Fahrenheit Scale (used in the US) |

They both measure the same thing (temperature!), but use different numbers

## Typical Temperatures in Daily Life

Description | °C | °F |

Moderate Oven | 180 | 356 |

Water boils | 100 | 212 |

Hot Bath | 40 | 104 |

Body temperature | 37 | 98.6 |

Beach weather | 30 | 86 |

Room temperature | 21 | 70 |

Cool Day | 10 | 50 |

Freezing point of water | 0 | 32 |

Very Cold Day | −18 | 0 |

Extremely Cold Day (the same number!) | −40 | −40 |

## How to Convert the Temperature

Here are the simple formula to convert

- Celsius to Fahrenheit: Multiply by 9, then divide by 5, then add 32
- Fahrenheit to Celsius: Deduct 32, then multiply by 5, then divide by 9

We can write each as a formula like this:

Temperature Converision | Formula |

°C → °F | (°C × 9/5) + 32 =….°F |

°F → °C | (°F − 32) x 5/9 = …. °C |

**Example**s

**Convert 30° Celsius to Fahrenheit**

°C → °F

30 °C = (30 × 9/5 + 32) °F

30 °C = (54 + 32) °F

30 °C = 96 °F

**Convert 95° Fahrenheit to Celsius**

95 °F = ((95 − 32) × 5/9)° C

95 °F = (63 × 5/9)° C

95 °F = 35 °C

Interisting Fact

Temperature is actually a measurement of how fast an objects particles are moving.
