How to Convert Millimeters Of Mercury to Atmospheres

Example: How many Atmospheres are equivalent to 71.75 Millimeters of Mercury?


As;

1 Millimeters of Mercury = 0.001316 Atmospheres

71.75 Millimeters of Mercury = Y Atmospheres

Assuming Y is the answer, and by criss-cross principle;

Y equals 71.75 times 0.001316 over 1

(i.e.) Y = 71.75 * 0.001316 / 1 = 0.094423 Atmospheres

Answer is: 0.094423 Atmospheres are equivalent to 71.75 Millimeters of Mercury.
