SUMMARY
Anders Celsius defined the temperature scale using water as a benchmark, establishing 0°C at the boiling point and 100°C at the freezing point. This original definition was later reversed by Carl Linnaeus and others to the current standard, where 0°C represents the freezing point and 100°C the boiling point of water. The choice of water was due to its accessibility and ease of use, despite the complications arising from pressure variations affecting the boiling point.
