## 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

## Examples

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.
