Celsius is the correct modern name for the temperature scale, while centigrade is an older term for the same scale.
I remember seeing both words in school books and weather reports and thinking they described two different systems. That confusion is very common.
Many people search “centigrade or celsius” because both terms appear in science and daily life. The good news is simple: they refer to the same temperature scale, but one is official and widely accepted today.
Once you understand the history and usage, choosing the right term becomes easy.
Centigrade or Celsius : Quick Answer
Centigrade = an older name for the temperature scale based on 100 degrees between freezing and boiling
Celsius = the official modern name for the same temperature scale used worldwide
Examples:
- Water freezes at 0°C (Celsius)
- Older texts may say 0 degrees centigrade
Simple rule:
Celsius → modern and correct
Centigrade → old but understandable
