The atmospheric pressure on your head is approximately 105 Pascals (Pa).
While this pressure might seem immense, we don't feel it because our bodies are designed to withstand it. This is due to the fact that the internal pressure from the air and blood inside our bodies counteracts the external atmospheric pressure, creating a balanced state.
In more familiar units, 105 Pa is roughly equivalent to:
- 1.05 x 105 N/m2 (Newtons per square meter)
- 1.05 bar
- About 1 atmosphere (atm)
Because the pressure inside and outside our bodies are equal, we don't experience the crushing force one might expect. This balance is crucial for our physiological functions.
