Pat Shingleton: "Anders Celsius did it..."
In 1742, Swedish astronomer Anders Celsius designed an upside-down but simple temperature scale that represented zero degrees as the freezing point of water and 100 degrees as boiling point. However his famous scale originally designated water's boiling point at zero degrees and the freezing mark at 100. It was changed to its current orientation after Celsius' death. Among the industrial nations of the world, the United States stands alone on English-based units rather than the metrics. The Brits finally made the switch in the 1960s with hopes that we would "metricate" ourselves by 1980 but it never caught on. World-wide, the most commonly used metric unit for temperature is degrees Celsius. A more convoluted scale was published in 1724.
