Oh, isn't that just a fascinating thought? The air pressure around us is usually about 14.7 pounds per square inch at sea level. It's like a gentle hug from Mother Nature, supporting us and keeping everything in balance. Just take a moment to appreciate how the world around us works together in harmony.
Well, isn't that an interesting question! The weight of the air in our atmosphere pressing down on Earth is about 14.7 pounds per square inch at sea level. It's like a gentle hug from nature, always surrounding us and keeping everything in balance. Just imagine all the beautiful landscapes and creatures that thrive under this gentle pressure.
Your ears pop on a mountain when there's a difference in air pressure between your inner ear and the air outside. The air in your inner ear exchanges pretty slowly. And since the air is much thinner at the top of the mountain than it is near the bottom, if you go down quickly enough (like by driving) the pressures can't equalize gradually. The higher pressure air at the bottom of the mountain presses on your eardrums until they "pop" and the pressure equalizes. That can hurt!

A kilopascal is a thousand pascal - a unit of pressure. "Absolute" means the actual pressure - this is in contrast to measuring a pressure DIFFERENCE (usually, how much higher some pressure is, compared to atmospheric pressure).
The average air pressure at sea level is about 14.7 pounds per square inch (psi) or 101.3 kilopascals (kPa). This pressure is due to the weight of the air molecules in the Earth's atmosphere above us pressing down on our bodies.
Going farther up into air, pressure decreases. Going down, pressure increases. When you think about it, more air is pressing down on you when you are standing on earth because more is on top of you. When you are up in the air, there isn't as much air pressing on you which shows that there isn't as much pressure. The same concept applies when under water; The farther you go under, more water is pressing on you than when you are more towards the surface which=more pressure (underwater).
The lower you go in the sea, the greater the water pressure, because of all the water above you, pressing down with its weight. To avoid being crushed by the water pressure, fish have an internal body pressure that is equal to that of the external water pressure. When the fish are raised to the surface rapidly, their internal pressure then is much greater than the air pressure, and it can cause their bodies to burst. If they are raised more slowly, the pressure has a chance to equalize. (Exactly the same reasoning to explain why an astronaut's body would burst if he forgot to get into his space suit before he stepped out on the veranda and began a space walk.)

A human is under an average pressure of about 14.7 pounds per square inch (psi) at sea level on Earth due to the weight of the atmosphere pressing down on them. This pressure decreases at higher altitudes and increases underwater.
You should aim to distribute your weight evenly on both feet without excessively pressing down on the floor. It's important to maintain a relaxed posture to avoid strain on your muscles and joints. Listen to your body and adjust the pressure as needed for comfort and balance.
Newborns's bodies are alot smaller. It doesn't take much pressure to get around the body.
roughly 14.6 pounds
The atmospheric pressure at sea level is 14.7 pounds per square inch (14.7 psi)
Considering this question is marked as iOS, I will tell you that no iOS device is pressure sensitive. Instead, they are heat sensitive. This allows you to interact with the touchscreen without needing to press down hard. To answer your question, pressing down hard on your phone will not really make a difference, not unless you press hard enough to crack the screen open.
They have evolved to deal with it by exerting an equal amount of pressure outwards as the average amount of pressure that is pressing down on them from above. Humans have done the same, since we are bearing the weight of the entire atmosphere but never notice! Internally, we are exerting the same pressure outwards to balance it. Certainly this is not as much as at the bottom of the ocean, but without this mechanism we would be crushed.
Pressure certainly does increase in a water line going down hill. This is because the weight of the water pulls it.
