Comparison of vacuum levels
Thread Content
-Which has a higher vacuum level, 0.1 or -0.01? I know that when comparing numerical values, -0.01 is definitely larger
The larger the absolute value of that number, the greater the degree of vacuum.
-A value of 0.1 is simply a matter of the magnitude being negative.
Theoretically, the larger the absolute value of a negative number, the higher the vacuum level. However, in practice, many people still hold to the conventional way of thinking, believing that it is the numerical value itself that matters. I was misled on the spot while asking people about changes in vacuum level, and it wasn’t until I realized it defied common sense that I understood I had made a mistake: Q
Think about the difference between 0.1 and 0.01; achieving which one is more difficult determines the higher the vacuum level required
First of all, this number doesn’t represent the vacuum level at all; rather, it indicates gauge pressure； It represents the degree of vacuum; it should be a non-negative value, within the range of 0-0.1 MPa ； In terms of gauge pressure, -0.1 represents a lower pressure, which means a higher level of vacuum
