High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa ). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 5.27×10^8 Pa , what is its running pressure in torr?

133.32 Pa = 1 torr
5.27*10^8 Pa * 1torr/133.32Pa=3.95*10^6 torr
5.27*10^8 Pa * 1torr/133.32Pa=3.95*10^6 torr

5.27E8 Pa= 3.95E6 torr
