About

He was born in 1701 in Uppsala, Sweden, into a family of scientists. Celsius became a professor of astronomy at Uppsala University and made significant contributions to the field of astronomy. In the early 18th century, Celsius observed the aurora borealis and conducted several expeditions to measure the Earth's shape and size. His work on geodesy, the study of Earth's physical properties and shape, earned him recognition among his contemporaries. Celsius is most famous for his invention of the Celsius temperature scale, also known as the centigrade scale. He proposed to divide the temperature range between the freezing and boiling points of water into 100 equal parts. This scale was later widely adopted and became the standard system for measuring temperature in most countries. Apart from his work on temperature scales, Celsius also made important contributions to understanding the behavior of gases, particularly how their volume varies with changes in temperature. He developed a scientific law, known as the Celsius law, which states that the volume of a gas is inversely proportional to its temperature at constant pressure. This law laid the groundwork for future advancements in the field of thermodynamics. Despite his influential contributions, Celsius did not live to see the widespread adoption of his temperature scale. He died in 1744 at the age of 42. However, his legacy lives on, and the Celsius scale remains one of the fundamental units of measurement used worldwide. In recognition of his significant scientific achievements, Celsius was posthumously honored through various tributes. The Celsius temperature scale was officially adopted by the International System of Units (SI) in 1948, and a crater on the Moon was named after him. Anders Celsius's life and work continue to be studied and appreciated for his pioneering advancements in the fields of astronomy, geodesy, and thermodynamics.
