Celsius to Fahrenheit Converter

A Celsius to Fahrenheit converter is a simple tool that converts temperature units from the Celsius to the Fahrenheit scale. Different countries use different temperature scales, and this converter serves as bridge between temperature scales ensuring accurate temperature conversion.

Short definition of Celsius

Celsius (°C) is a temperature scale based on the freezing point of water at 0°C and the boiling point of water at 100°C under standard atmospheric pressure (1 atm). It was developed by Swedish astronomer Anders Celsius in 1742. Celsius is part of the metric system, which is widely used in research and most countries.

Definition of Fahrenheit (°F)

Fahrenheit (°F) is another crucial temperature scale developed by German physicist Daniel Gabriel Fahrenheit in 1724. In the Fahrenheit temperature scale, the freezing point of water is 32°F, and the boiling point of water is 212°F, under standard atmospheric pressure (1 atm).

°C to °F conversion formula

To convert Celsius to Fahrenheit, you can use this simple mathematical formula which adjusts the differences in the scales.

Fahrenheit = (Celsius × 9/5​) + 32

Multiply by 9/5: The Celsius scale has a more significant degree change than the Fahrenheit scale. A 1°C change equals a 1.8°F change (9/5=1.8). To convert the temperature difference from C to °F, multiply by 9/5.

Adding 32: The Fahrenheit scale starts at 32°F for the freezing point of water, whereas the Celsius scale starts at 0°C. The difference in the measurement is compensated for by adding 32.

Example 1:
Convert 25°C to Fahrenheit.
Fahrenheit = (25 × 9/5) + 32
Fahrenheit =(25 × 1.8) + 32
°F = 45 + 32 = 77 Fahrenheit

Example 2:
Convert -10°C to Fahrenheit.
Fahrenheit = (-10 × 9/5) + 32
Fahrenheit =(-10 × 1.8) + 32
°F = −18 + 32 = 14 Fahrenheit

Table 1 displays temperature values in Celsius, Fahrenheit, and Kelvin for various reference points.

1. What temperature is 20°C to F?

20 Celsius is equivalent to 68°F.

Fahrenheit = (Celsius × 9/5​) + 32

100°F is approximately 37.8°C, not exactly 40°C.
