How to convert temperature units

Certainly, here are the formulas to convert between the different temperature units:

  1. Celsius to Fahrenheit:

    • Formula: °F = (°C x 1.8) + 32
    • Example: Convert 25°C to Fahrenheit. °F = (25 x 1.8) + 32 °F = 77°F
  2. Fahrenheit to Celsius:

    • Formula: °C = (°F - 32) / 1.8
    • Example: Convert 68°F to Celsius. °C = (68 - 32) / 1.8 °C = 20°C
  3. Celsius to Kelvin:

    • Formula: K = °C + 273.15
    • Example: Convert 20°C to Kelvin. K = 20 + 273.15 K = 293.15 K
  4. Kelvin to Celsius:

    • Formula: °C = K - 273.15
    • Example: Convert 300 K to Celsius. °C = 300 - 273.15 °C = 26.85°C
  5. Fahrenheit to Kelvin:

    • Formula: K = (°F + 459.67) x 5/9
    • Example: Convert 50°F to Kelvin. K = (50 + 459.67) x 5/9 K = 283.15 K
  6. Kelvin to Fahrenheit:

    • Formula: °F = (K x 9/5) - 459.67
    • Example: Convert 300 K to Fahrenheit. °F = (300 x 9/5) - 459.67 °F = 80.33°F

Temperature units information

Temperature is a measure of the degree of hotness or coldness of an object or substance. There are several temperature scales and units that have been developed over time, with the most commonly used units being Celsius (°C), Fahrenheit (°F), and Kelvin (K).

Celsius is a metric scale that was proposed by Swedish astronomer Anders Celsius in 1742. In this scale, the freezing point of water is defined as 0°C and the boiling point of water is defined as 100°C at standard atmospheric pressure. Celsius is widely used in scientific and everyday applications around the world, except for the United States, which mostly uses the Fahrenheit scale.

The Fahrenheit scale was developed by German physicist Daniel Gabriel Fahrenheit in 1724. In this scale, the freezing point of water is defined as 32°F and the boiling point of water is defined as 212°F at standard atmospheric pressure. Fahrenheit is commonly used in the United States and some other countries, but it has been largely replaced by Celsius in scientific and international contexts.

Kelvin is an absolute scale that was proposed by British physicist William Thomson, also known as Lord Kelvin, in 1848. In this scale, the zero point is defined as absolute zero, the theoretical temperature at which all molecular motion stops. The Kelvin scale is commonly used in scientific applications, especially in fields such as physics and chemistry.

Temperature Examples

Here are the examples of reference temperatures in kelvin (K), Celsius (°C), and Fahrenheit (°F):

What is the most commonly used unit of temperature?

The most commonly used unit of temperature depends on the region and context. In scientific and industrial contexts, Kelvin (K) is often used as the standard unit of temperature, especially in thermodynamics and in measuring high and low temperatures. In everyday life, Celsius (°C) is the most commonly used unit of temperature, especially in countries that use the metric system. Fahrenheit (°F) is still commonly used in the United States for weather reports and in some other applications, such as cooking.

It's worth noting that the International System of Units (SI) defines Kelvin as the standard unit of temperature, and Celsius is derived from Kelvin by subtracting 273.15. However, in many countries, Celsius is still the preferred unit for everyday use, while Kelvin is used mainly for scientific and technical purposes.
