How many atmospheres is 1 torr?

1 torr is about 0.001316 atmospheres.

How many torr is 1 atmosphere?

1 atmosphere equals 760 torr.

What is the difference between torr and atmospheres?

Both measure pressure, but they are commonly used in different contexts. Torr are used in lab work and vacuum technology. Atmospheres are used as a reference for standard atmospheric pressure.

Where are torr and atmospheres used?

In practice: Torr are used in lab work and vacuum technology. Atmospheres are used as a reference for standard atmospheric pressure.

Why does 1 torr equal 0.001316 atmospheres?

Because pressure units are defined with a fixed relationship (often relative to the pascal). To convert, multiply by that factor.
