What units of measurement are used to characterize atmospheric pressure?

For atmospheric pressure, a special non-systemic unit of pressure measurement was introduced, which is called “atmosphere” and is equal to the pressure of the air layer above the measurement point. And with the main unit of measurement of pressure – pascal – the atmosphere is related as follows: 1 atmosphere is equal to about 101 thousand pascals. I must say that now there are many different units of pressure, which complicates the work of scientists and they tend to gradually displace non-systemic units, which include the atmosphere.
