What is 5 atmospheres in feet?
The ATM or “atmospheres” is the amount of pressure a watch can withstand. 5ATM will withstand pressures equivalent to about 50 meters, or 164 ft under water.
How many feet is 3bar?
30 meters/100 feet/3 bar: General water resistant watches can withstand minor moisture from splashing, but should not be worn for swimming, diving, bathing, or showering.
How deep is an atmosphere in water?
33 feet
One atmosphere is approximately equal to 33 feet of sea water or 14.7 psi, which gives 4.9/11 or about 0.445 psi per foot.
How do you convert atm to feet of water?
Quick conversion chart of atm to ft water
- atm to ft water = 33.89854 ft water.
- atm to ft water = 67.79708 ft water.
- atm to ft water = 101.69562 ft water.
- atm to ft water = 135.59415 ft water.
- atm to ft water = 169.49269 ft water.
- atm to ft water = 203.39123 ft water.
- atm to ft water = 237.28977 ft water.
How many ATA is 99 feet?
That’s 4 atmospheres of pressure (99 feet ÷ 33 + 1 = 4 ATA or 30 meters ÷ 10 + 1 = 4 ATA).
What is a 5 ATM water rating?
The above devices have been certified to 5ATM standards. This means that they are water resistant to up to 50 metres in depth for 10 minutes. They are now suitable for low-velocity and shallow-water activities, including swimming. You can enjoy more freedom to explore, stay connected, and capture the adventure.
What depth is 20bar?
200 meters
A 20 bar water resistant watch is strong enough to hold water pressure on a par with a depth of 200 meters.
What depth is 1bar?
0 meters
Basic Physics of Freediving – Dealing With Pressure
| Depth | Bar/atmospheres (ATM) of pressure | Volume of air in our bodies |
|---|---|---|
| 0 meters (surface) | 1 | 1 |
| 10 meters | 2 | 1/2 |
| 20 meters | 3 | 1/3 |
| 30 meters | 4 | 1/4 |
How deep can a human dive?
That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
How deep underwater is 3 ATM?
3ATM (30 meters= ~100 ft.): This is the initial level of protection/water resistance.
How many feet deep is 2 atmospheres?
This means that at a depth of 33 feet deep in the ocean, there is a total pressure of 29.4 pounds per square inch (psi). This would be 2 ATMs of pressure.
How many atm Can a human survive?
A person can withstand perhaps 100 atmospheres of pressure if they aren’t breathing air – divers do it. If they are breathing air, the limit is just a handful of atmospheres.
