How to Calculate Celsius: A Clear and Confident Guide
Calculating temperatures in Celsius is a basic but important skill that everyone should know. Celsius is a metric unit of temperature used in most countries around the world. It is named after the Swedish astronomer Anders Celsius, who first proposed the scale in 1742. Celsius is also known as the centigrade scale because there are 100 degrees between the freezing point (0°C) and the boiling point (100°C) of water at standard atmospheric pressure.
To calculate temperatures in Celsius, you need to know the formula for converting them from Fahrenheit. Fahrenheit is a non-metric unit of temperature used primarily in the United States and a few other countries. The formula for converting Fahrenheit to Celsius is (°F - 32) x 5/9 = °C. This means that you subtract 32 from the Fahrenheit temperature, multiply the result by 5, and then divide by 9 to get the Celsius temperature. Conversely, to convert Celsius to Fahrenheit, you use the formula (°C x 9/5) + 32 = °F. This means that you multiply the Celsius temperature by 9, divide by 5, and then add 32 to get the Fahrenheit temperature.
Understanding Temperature Units
Temperature is a measure of the degree of hotness or coldness of an object or substance. It is a physical quantity that describes the direction of heat flow. Temperature is measured using various temperature scales such as Celsius, Fahrenheit, and Kelvin.
Celsius Scale
The Celsius scale is a metric temperature scale that is widely used in scientific and everyday applications. It is based on the freezing and boiling points of water. The Celsius scale is divided into 100 equal parts or degrees between the freezing point of water (0°C) and the boiling point of water (100°C). The Celsius scale is denoted by the symbol °C.
Fahrenheit Scale
The Fahrenheit scale is a temperature scale used primarily in the United States and a few other countries. It is based on the freezing and boiling points of water, but the scale is divided into 180 equal parts or degrees between the freezing point of water (32°F) and the boiling point of water (212°F). The Fahrenheit scale is denoted by the symbol °F.
Kelvin Scale
The Kelvin scale is an absolute temperature scale that is used in scientific applications. It is based on the theoretical concept of absolute zero, which is the lowest possible temperature that can be achieved. The Kelvin scale is divided into 100 equal parts or degrees between absolute zero (0 K) and the triple point of water (273.16 K). The Kelvin scale is denoted by the symbol K.
It is important to understand the differences between these temperature scales and how to convert between them. One can use conversion formulas or online converters to convert between Celsius, Fahrenheit, and Kelvin.

To convert Fahrenheit to Celsius, you can use the following formula:
°C = (°F - 32) / 1.8
Knowing how to convert between Celsius and Fahrenheit is important for a variety of applications, including weather forecasting, cooking, and scientific research.
Converting Fahrenheit to Celsius
The Formula
To convert a temperature from Fahrenheit to Celsius, you need to use the formula:
C = (F - 32) x 5/9
Where C is the temperature in Celsius and F is the temperature in Fahrenheit.
Step-by-Step Calculation
To convert Fahrenheit to Celsius, follow these steps:
- Subtract 32 from the Fahrenheit temperature.
- Multiply the result by 5.
- Divide the result by 9.
The final result is the temperature in Celsius.
Example Conversion
Let's say you have a temperature of 68 degrees Fahrenheit and want to convert it to Celsius.
- Subtract 32 from 68:
68 - 32 = 36 - Multiply 36 by 5:
36 x 5 = 180 - Divide 180 by 9:
180 / 9 = 20
Therefore, 68 degrees Fahrenheit is equal to 20 degrees Celsius.
It's important to note that Fahrenheit and Celsius are two different temperature scales, and the conversion formula is necessary to convert between them.
Converting Kelvin to Celsius
The Kelvin Scale
Kelvin is a unit of temperature measurement in the International System of Units (SI). It is based on the absolute zero point, which is the theoretical temperature at which all matter would have zero thermal energy. The Kelvin scale is used in scientific and engineering applications where precise temperature measurements are required.
The Conversion Formula
To convert a temperature from Kelvin to Celsius, you can use the following formula:
°C = K - 273.15
Where °C represents the temperature in Celsius and K represents the temperature in Kelvin.
Practical Example
Suppose you have a temperature of 300 Kelvin and you want to convert it to Celsius. Using the formula above, you would subtract 273.15 from 300 to get:
°C = 300 - 273.15 = 26.85
Therefore, a temperature of 300 Kelvin is equivalent to 26.85 degrees Celsius.
It is important to note that Kelvin and Celsius are both units of temperature measurement, but they have different scales. Kelvin is an absolute scale, while Celsius is a relative scale. This means that Kelvin is always positive and does not have negative values, whereas Celsius can have negative values.
Converting Kelvin to Celsius is a simple process that can be done using the conversion formula. It is important to understand the difference between the Kelvin and Celsius scales and when each one should be used.
