Exact definition of 5E-5pa
Thread Content
Dear sea friends, does the vacuum level of 5E-5pa mean 0.00005pa? If so, where does the zero point for this 0.00005 come from? Is it a decrease of 0.000005 from atmospheric pressure, or an increase of 0.000005 in absolute pressure? Atmospheric pressure? Absolute zero pressure? Is there any watch that can measure accurately?

It’s just a little bit higher than absolute pressure 0, right?
