Frequently Asked Questions
Gauge pressure is measured relative to the surrounding atmospheric pressure, while absolute pressure is measured relative to a perfect vacuum (zero pressure). Most pressure gauges, like tire gauges, read gauge pressure.
At high altitudes, the lower atmospheric pressure causes water to boil at a lower temperature, meaning food cooked in boiling water takes longer to cook. Recipes often need adjustments for altitude.
Too low pressure can lead to excessive tire flexing, increased heat buildup, reduced fuel efficiency, and uneven wear. Too high pressure can reduce tire traction, lead to a harsher ride, and cause uneven wear in the center of the tire.
Yes, Torr is a unit of pressure defined as exactly 1/760 of a standard atmosphere, which is practically equivalent to one millimeter of mercury (mmHg). They are often used interchangeably, especially in vacuum and medical applications.
Atmospheric pressure changes are key indicators for weather forecasting. High pressure often indicates stable, clear weather, while low pressure systems are usually associated with storms and unstable weather.
Hydrostatic pressure is the pressure exerted by a fluid at rest due to the force of gravity. It increases proportionally with depth in a fluid.
Yes, while blood pressure is specifically measured in mmHg, you can use the converter to see what those values would be in other units like kPa, though mmHg remains the standard for medical diagnosis.
