SDI DIVEMASTER EXAM QUESTIONS AND CORRECT ANSWERS
|2026/2027 UPDATED |GUARANTEED PASS.

Pressure - Answer -The force or weight pressing upon a surface.




Barometer - Answer -An instrument that measures atmospheric pressure.




Ambient Pressure - Answer -Also known as absolute pressure, this refers to the total force being
exerted simultaneously by all existing sources of pressure.




Atmospheric Pressure - Answer -One barometric unit of measure (1 bar or 1kg/cm2)

One atmospheric unit of measure (1 atm or 14.7lbs/in2)

1 bar = 1 atm




Pressure increase by 1 bar or 1 atm - Answer -Every 10m or 33ft of seawater




Gauge Pressure - Answer -The manner in which a diver's instruments measure and display
pressure-related information. It disregards atmospheric pressure and only provides a
measurement of the actual force being exerted by another source of pressure.

, Bar Conversion - Answer -= psi / 14.7




Psi Conversion - Answer -= bar x 14.7




Meters Conversion - Answer -= feet / 3.3




Feet Conversion - Answer -= meters x 3.3




Depth to Pressure Calculation (Seawater) - Answer -= (meters / 10) + 1

= (meters + 10) / 10

= (feet / 33) + 1

= (feet + 33) / 33




Pressure to Depth Calculation (Seawater) - Answer -= (bar - 1) x 10

= (bar x 10) - 10

= (atm - 1) x 33

= (atm x 33) - 33




Depth to Pressure Calculation (Freshwater) - Answer -= (meters / 10.3) + 1

= (meters + 10.3) / 10.3
