About converting Bars to Torr
Bars (bar) and Torr (Torr) are both units of pressure, so converting between them is a single multiplication: multiply your Bars figure by 750.0617. Ten Bars comes to 7,500.62 Torr, and a hundred works out at 75,006.17 Torr.
Rule of thumb: going from Bars to Torr multiplies, so the figure always grows — one Bar is already 750.0617 Torr. If your answer came out smaller, you have the conversion the wrong way round.
What is a Bar?
The bar is not an SI unit, but it is accepted for use alongside them, and it earns that place by sheer convenience: it was chosen to sit close to average atmospheric pressure, so "one bar" reads as roughly what the air is doing right now. It dominates European industry — compressed air, hydraulics, scuba cylinders, espresso machines and tyre pressures are all quoted in bar. Its subdivision the millibar had a long career in weather forecasting before being quietly replaced by the hectopascal, which is exactly the same size, so nothing on the old charts had to change.
What is a Torr?
The torr is named after Evangelista Torricelli, who invented the mercury barometer and in the process produced the first sustained vacuum anyone had made. The unit fits that legacy exactly: it is very nearly the pressure of one millimetre of mercury, and it is still the working unit of vacuum technology, where gauges read in torr and in decimal fractions of it. Its most familiar relative is not in a laboratory at all — blood pressure is quoted in millimetres of mercury, essentially the same size, so a reading of 120 over 80 is a pressure measurement in all but name.
To put both in perspective: a scuba tank is filled to about 200 bar, while a rough vacuum pump pulls down to about 0.1 torr.

Is this Bars to Torr conversion exact?
The definition is exact — Bars and Torr are both fixed against the same base by international agreement — but the decimal shown here is rounded for readability, because the true ratio does not terminate. For engineering or scientific work, carry more decimal places than this page displays.
