About Newton

Newton (°N) was devised by Isaac Newton around 1700 and published anonymously in 1701. The scale places water's freezing point at 0°N and boiling point at 33°N - a choice that allowed body temperature to fall at approximately 12°N. Newton used linseed oil as the thermometric fluid and described his scale in the Philosophical Transactions of the Royal Society. Although never widely adopted, it is historically significant as one of the earliest systematic temperature scales and directly inspired Ole Rømer, who visited Newton, and later Daniel Gabriel Fahrenheit, who built upon Rømer's work.

About Celsius

Celsius (°C) is the most widely used temperature scale worldwide, named after Swedish astronomer Anders Celsius (1742). It's based on the freezing point of water at 0°C and boiling point at 100°C under standard atmospheric pressure (1 atmosphere). This makes it intuitive for daily use: room temperature is around 20-22°C, body temperature is 37°C, and a hot summer day might reach 35-40°C. It's the standard in science, medicine, and weather reporting in most countries.
