I can vouch for this from firsthand experience. It is also very good to know both units of pressure measurement.
#60 psi to bar how to
This is why it is so important to know what these terms mean, and how to read your pressure gauge underwater. It will tell us using pressure measurements of bar or PSI. This means we need to know how much is in our tank at all times so we can plan our dive and decide when to go up safely.Ī submersible pressure gauge (SPG) will tell us how much gas/pressure is in our tank. What is Bar or PSI measurements used for?Īs scuba divers, we are breathing from our SCUBA unit, and relying on the gas inside our tanks/cylinders. These countries use what is called PSI or pounds per square inch (lb./in 2) for measuring pressure.Īs you can see from above, what system you learn to dive with will very much depend on where you learn to dive (or where your instructor is from!). From these countries, the USA unsurprisingly has the largest diving community. Imperial measurements are now only used by The United States of America, Myanmar and Liberia.

In fact, only three countries in the world don’t use this system (more on those later) so chances are you will be learning to use bar when you first start out scuba diving. This is the most commonly used system around the world in scuba diving. Pressure is the measure of force exerted on an object and bar is the measure of how much force is being exerted.īar is used by the metric system for measuring pressure Kilograms per square centimeter (Kg/cm 2). PSI pressure, what they are, the differences between them, and how it affects us while diving.įirst up is a bit of information on the two most commonly used ways of measuring pressure. What is Bar Pressure & PSI Pressure in Scuba Diving? Photo: Kris Mikael Krister / UnsplashĪs a scuba diver, you will certainly come across the terms ‘Bar’ and/or ‘PSI.’ But what exactly do they mean? Well, as a scuba instructor, I hear this question a lot, so here we are going to look at what is Bar pressure vs.
