Understanding Temperature Scales

Temperature is a physical quantity that expresses hot and cold. Different temperature scales are used around the world for various scientific and everyday purposes.

Celsius (°C)

The Celsius scale, also known as the centigrade scale, is used by most countries worldwide. On this scale:

  • Water freezes at 0°C and boils at 100°C at standard atmospheric pressure
  • Normal human body temperature is approximately 37°C
  • Room temperature is typically around 20-25°C

Fahrenheit (°F)

The Fahrenheit scale is primarily used in the United States. On this scale:

  • Water freezes at 32°F and boils at 212°F at standard atmospheric pressure
  • Normal human body temperature is approximately 98.6°F
  • Room temperature is typically around 68-77°F

Kelvin (K)

The Kelvin scale is the SI base unit of temperature and is used primarily in scientific contexts. On this scale:

  • 0K is absolute zero (-273.15°C), the theoretical lowest possible temperature
  • Water freezes at 273.15K and boils at 373.15K at standard atmospheric pressure
  • The Kelvin scale uses the same increment size as Celsius
  • Unlike Celsius and Fahrenheit, Kelvin does not use the degree symbol (°)

Temperature Conversion Formulas

Celsius to Fahrenheit:

°F = (°C × 9/5) + 32

Fahrenheit to Celsius:

°C = (°F - 32) × 5/9

Celsius to Kelvin:

K = °C + 273.15

Kelvin to Celsius:

°C = K - 273.15

Fahrenheit to Kelvin:

K = (°F - 32) × 5/9 + 273.15

Kelvin to Fahrenheit:

°F = (K - 273.15) × 9/5 + 32

Interesting Temperature Facts

  • The hottest temperature ever recorded on Earth was 56.7°C (134°F) in Death Valley, California in 1913
  • The coldest natural temperature ever recorded on Earth was -89.2°C (-128.6°F) at the Soviet Vostok Station in Antarctica in 1983
  • Scientists have achieved temperatures of less than one billionth of a degree above absolute zero in laboratory conditions
  • The Celsius and Fahrenheit scales intersect at -40 degrees (-40°C = -40°F)
