How deep is 20 bars?? I have a G-Shock watch and it says that it is water resistant to 20 bars. How deep is that in english?

Classe d'étanchéité (20 bars/ 200M)
Parfait pour nager et faire de la plongée sans équipement : la montre est étanche jusqu'à 20 bars, l'équivalent de 200 mètres. Les indications en mètres ne se réfèrent pas à la profondeur de plongée, mais à la pression atmosphérique, utilisée dans le cadre du contrôle d'étanchéité. (ISO 2281)

1bar is 15 psi (or 14.7 to be perfect)

PRESSURE:

1 atm = 14.7 psi = 1.03 kilograms per square centimeter = 1 bar

1 deg F makes a 5 psi (approx.) change in pressure in a SCUBA tank.

Airplane cabin pressure @ 30,000 ft = atm @ 8000 ft = 10.5 psi (approx.)

In salt water: (Depth in feet)

atm = Depth / 33

ata = (Depth / 33) + 1

psi = Depth x 0.445

psia = (Depth x 0.445) + 14.7

In fresh water: (Depth in feet)

atm = Depth / 34

ata = (Depth / 34) + 1

psi = Depth x 0.432

psia = (Depth x 0.432) + 14.7


About 675 feet in saltwater, 700 feet in freshwater



Uhh...thanks!!! Now my head hurts!!

I hope doubt I'll ever get that deep!
