How many feet are in a ATM?
How many feet are in a ATM?
34 feet
And now for a little math! 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 .
What does 3 ATM water resistant mean?
3 ATM (30 m) Protected against splashes from rain, hand washing, etc. Not suitable for showering or swimming. 5 ATM (50 m) Suitable for withstanding short periods of water immersion, such as light swimming.
Can you swim with a 3 ATM watch?
3 ATM/bar/30m: This watch are resistant against rain and splashes. 5 ATM/bar/50m: This watch is waterproof and can be worn during swimming without jumping from a diving board. They are not qualitfied to snorkle or dive. If you plan on jumping off cliffs and diving, don’t wear this watch.
Is 3 atm a lot?
Rule of thumb: 1–3ATM / ‘Water resistant’ = ok to get wet when washing hands or doing the dishes or getting caught in the rain. 3–10ATM = ok in the shower, not recommended to swim.
What is 5 atmospheres in feet?
5 ATM/ 5 Bar/ 50 Meters / 165 Feet.
How many atmospheres are underwater?
One atmosphere (101.325 kPa or 14.7 psi) is also the pressure caused by the weight of a column of fresh water of approximately 10.3 m (33.8 ft). Thus, a diver 10.3 m underwater experiences a pressure of about 2 atmospheres (1 atm of air plus 1 atm of water).
How deep is 50m in a pool?
The Olympic sized pool is 165 feet long by 56 feet wide (8 lap lanes, each 7 feet wide). It holds 490,000 gallons (almost 1/2 million gallons). Depth begins at 3.5 feet and gradually slopes down to 13 feet at the deepest end.
How long can I swim with a 5ATM watch?
5ATM will withstand pressures equivalent to about 50 meters, or 164 ft under water. It is important to note that this is a measure of pressure NOT depth. 5ATM doesn’t mean the watch can be used diving to a depth of 50 meters.
What does 10 ATM on a watch mean?
3ATM is splash resistant. Ok for wearing in the rain, hand washing, other occasional contact with water. Most Grace & Co fashion watches are 3ATM. 5ATM is suitable for swimming, fishing, other outdoor activities. 10ATM is suitable for snorkelling and swimming but not for scuba diving.
What is 2.5 atm in PSI?
2.5 atm = 36.74 pounds per square inch Formula: multiply the value in atm by the conversion factor ‘14.6959488036’. So, 2.5 atm = 2.5 × 14.6959488036 = 36.739872009 pounds per square inch.
What depth is 1bar?
At sea level, the pressure of the air that surrounds us equal to 1 bar, which is sometimes referred to as 1 atmosphere….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 |
What does 10atm mean?
Water Rating Definitions
| Water Rating | Definition |
|---|---|
| 1 ATM | Withstands pressures equivalent to a depth of 10 meters |
| 3 ATM | Withstands pressures equivalent to a depth of 30 meters |
| 5 ATM, Swim | Withstands pressures equivalent to a depth of 50 meters |
| 10 ATM | Withstands pressures equivalent to a depth of 100 meters |
Is 3 atm waterproof?
The back of the watch states the watch is 3ATM Water Resistant. This does not mean the watch is waterproof. 3ATM Water Resistant is often misinterpreted as waterproof to 3 meters or 30 meters.
What is the depth of 3 atm?
ATM is a detail included in the specs for most watches, but there are a surprising number of people who 3 ATM. = 30 meters (ft) depth.
What is meant by a 3 atm water resistant watch?
Instead, it is a shortening of the word “atmosphere,” and it refers to the amount of pressure exerted as you dive below sea level. As you dive, the atmosphere increases every 10 meters. This means, if you’ve seen a watch advertised as water-resistant up to 3 atm, it’s resistant up to 30 meters; likewise, 5 atm is 50 meters.
