Swedish astronomer who devised the centigrade thermometer (1701-1744)
"The modern Celsius scale is named after Anders Celsius, the Swedish astronomer who devised the centigrade thermometer in 1742."
Related to a metric temperature scale, originally defined as having the freezing point of water as 0 degrees and its boiling point as 100 degrees, at standard atmospheric pressure. The standardized definition has 0.01 °C as the triple point of water, and a difference in temperature of 1 °C corresponds to ¹⁄_(273.16) of the difference in temperature between the triple point and the absolute zero.
"In my spreadsheet, I typed "celsius" instead of "Celsius" because the formula was case-sensitive and wouldn't recognize the capital C."
