Understanding the Fahrenheit and Celsius Scales
The Fahrenheit Scale
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in the early 18th century. It is primarily used in the United States for everyday temperature measurements. The scale is based on three fixed points:
- The freezing point of water (32°F)
- The boiling point of water (212°F)
- The human body temperature (around 98.6°F)
The Celsius Scale
The Celsius scale, also known as the Centigrade scale, was created based on the freezing and boiling points of water, set at 0°C and 100°C respectively under standard atmospheric pressure. It is used worldwide, especially in scientific contexts.

How to Convert 68°F to Celsius: The Formula
The mathematical formula for converting Fahrenheit to Celsius is straightforward:
°C = (°F - 32) × 5/9
Applying this formula to 68°F:
- Subtract 32 from the Fahrenheit temperature:
- Multiply the result by 5/9 to get the Celsius equivalent.
Calculation:
°C = (68 - 32) × 5/9
°C = 36 × 5/9
°C = 36 × 0.5556
°C ≈ 20°C
Therefore, 68°F equals approximately 20°C.

Step-by-Step Guide to Convert Any Temperature from Fahrenheit to Celsius
Converting temperatures from Fahrenheit to Celsius can be simplified by following these easy steps:
Step 1: Subtract 32 from the Fahrenheit temperature
- Example: 68°F - 32 = 36
Step 2: Multiply the result by 5/9
- Example: 36 × 5/9 = 36 × 0.5556 ≈ 20°C
Step 3: Round to desired decimal places (if necessary)
- Usually, rounding to the nearest whole number or one decimal place is sufficient.
