Barometer is an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude. From Greek baros “weight” (from suffixed form of PIE root *gwere- (1) “heavy”) + -meter. The name probably was coined (and certainly popularized) by English scientist Robert Boyle (1627-1691). The instrument was invented 1643 by Italian physicist Evangelista Torricelli and was at first known as the Torricelli tube.
