## What is the pressure of the atmosphere in PSI?

Page Contents

14.7 psi

Commonly used in the U.S., but not elsewhere. Normal atmospheric pressure is 14.7 psi, which means that a column of air one square inch in area rising from the Earth’s atmosphere to space weighs 14.7 pounds. Normal atmospheric pressure is defined as 1 atmosphere. 1 atm = 14.6956 psi = 760 torr.

**How many PSI is the air?**

Since atmospheric pressure at sea level is around 14.7 psi (101 kilopascals), this will be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure.

**What is KSC in pressure measurement?**

A kilogram-force per centimetre square (kgf/cm2), often just kilogram per square centimetre (kg/cm2), or kilopond per centimetre square is a deprecated unit of pressure using metric units. In some older publications, kilogram-force per square centimetre is abbreviated ksc instead of kg/cm2.

### How heavy is 2atm?

Atmospheres to Kilogram force per square meter table

Atmospheres | Kilogram force per square meter |
---|---|

0 atm | 0.00 kg/m2 |

1 atm | 10332.27 kg/m2 |

2 atm | 20664.55 kg/m2 |

3 atm | 30996.82 kg/m2 |

**How much psi can a human take?**

The human body can withstand 50 psi (pounds per square inch) and that’s if it’s a sudden impact. However if it’s sustained pressure, the body can withstand up to 400 psi if the weight is gradually increased. Because the human skull is in an arch form, it can withstand large amounts of pressure.

**What is considered low atmospheric pressure?**

A barometric reading below 29.80 inHg is generally considered low, and low pressure is associated with warm air and rainstorms.

## Why we use kg cm2?

It is the metric equivalent of pounds per square inch (psi). 1 kg/cm2 equals 98,066.5 pascals. Similarly to psi, kg/cm2 is part of a group of pressure units that relate pressure with weight. This is convenient in applications where a pressure is applied to generate a load such as in material testing.

**At what depth will you reach 1 atm of pressure?**

34 feet

And now for a little math! 445 lbs per foot of depth. Fresh water being slightly lighter, requires a depth of 34 feet to equal 1 ATM, so fresh water exerts a pressure of 14.7 divided by 34, or . 432 lbs per foot of depth.

**Does atm increase with altitude?**

The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth’s atmospheric pressure at sea level is approximately 1 atm. As elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation.

### What’s the highest pressure ever recorded?

According to the Guinness Book of World Records, the highest barometric pressure ever recorded was 32.00″ set in Siberia, Russia on December 31, 1968. That’s like being 2,000 feet under the sea. The Upper Midwest pressure on Thursday will be the same as if you were 1,000 below the sea!
