48 degrees Fahrenheit equals approximately 8.8889 degrees Celsius.
To convert 48°F to Celsius, you subtract 32 from the Fahrenheit temperature, then multiply the result by 5/9. This calculation adjusts the scale difference between Fahrenheit and Celsius, providing the equivalent temperature in Celsius.

Conversion Formula
The formula to convert Fahrenheit (°F) to Celsius (°C) is: Celsius = (Fahrenheit – 32) × 5/9. This formula works because the Fahrenheit and Celsius scales have different zero points and increments. Fahrenheit starts at 32 for the freezing point of water, while Celsius starts at 0.
First, subtract 32 from the Fahrenheit value to adjust the zero point. Then multiply by 5/9 to scale from Fahrenheit degree size to Celsius degree size.
Step-by-step for 48°F:
- Subtract 32: 48 – 32 = 16
- Multiply by 5/9: 16 × 5/9 = 16 × 0.5555… = 8.8889
- Result: 8.8889°C
Conversion Example
- 68°F to Celsius:
- Subtract 32: 68 – 32 = 36
- Multiply by 5/9: 36 × 5/9 = 36 × 0.5555… = 20.0°C
- 104°F to Celsius:
- Subtract 32: 104 – 32 = 72
- Multiply by 5/9: 72 × 5/9 = 72 × 0.5555… = 40.0°C
- 32°F to Celsius:
- Subtract 32: 32 – 32 = 0
- Multiply by 5/9: 0 × 5/9 = 0°C
- 77°F to Celsius:
- Subtract 32: 77 – 32 = 45
- Multiply by 5/9: 45 × 5/9 = 25°C
- 50°F to Celsius:
- Subtract 32: 50 – 32 = 18
- Multiply by 5/9: 18 × 5/9 = 10°C

Conversion Definitions
Fahrenheit: A temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It is mainly used in the United States and some Caribbean countries. The scale was created by Daniel Gabriel Fahrenheit in 1724, based on three fixed points of temperature.
Celsius: A temperature scale in which water freezes at 0 degrees and boils at 100 degrees under normal atmospheric pressure. It is used by most countries worldwide and in scientific contexts. The scale was created by Anders Celsius in 1742 and is based on the decimal system.
Conversion FAQs
Can I convert Fahrenheit to Celsius by just subtracting 30?
Subtracting 30 from the Fahrenheit value gives a rough estimate but is not accurate. The correct method uses subtracting 32 and multiplying by 5/9. The 30-subtraction method can be off by several degrees, which matters for precise temperature needs.
Why do we multiply by 5/9 after subtracting 32?
Because the size of one degree Fahrenheit is different from one degree Celsius. Fahrenheit has 180 degrees between freezing and boiling of water, Celsius has 100 degrees. Multiplying by 5/9 adjusts the scale difference so the temperature matches the Celsius scale.
Is the conversion formula the same for negative Fahrenheit values?
Yes, the same formula applies regardless of positive or negative Fahrenheit temperatures. You subtract 32 and multiply by 5/9. For example, -4°F converts to approximately -20°C using the same formula.
How precise is the result when using decimal places in conversion?
The precision depends on how many decimal places you keep. The exact result can have many decimals, but rounding to 2-4 places is usually sufficient for everyday use. Scientific uses may require more precise decimal places.
Are there any shortcuts for mental conversion from Fahrenheit to Celsius?
Some mental shortcuts exist like subtracting 30 and halving the number for an estimate, but these are not exact. For a correct conversion, the formula with subtracting 32 and multiplying by 5/9 must be used.
