Pressure Converter is widely used in various fields:
Weather Data Analysis
Different pressure units are used by region and country. Japan uses hectopascals (hPa=mbar), the USA uses inches of mercury (inHg), and Europe uses millibars (mbar). Converting typhoon central pressure (e.g., 950 hPa) to PSI or atm enables international data comparison.
Engineering & Mechanical Design
Accurate pressure conversion is essential for hydraulic systems, pneumatic equipment, and pipe design. For example, tire pressure is expressed in PSI in the USA (e.g., 32 psi), bar in Europe (e.g., 2.2 bar), and kPa in Japan (e.g., 220 kPa). This tool easily converts between international and regional standards.
Physics Experiments & Calculations
In physics experiments, Pascal (Pa) is the SI base unit, but Torr and atmosphere (atm) are also widely used historically. For example, standard atmospheric pressure equals 1 atm = 101,325 Pa = 760 Torr = 1.01325 bar. Useful for comparing experimental results across different unit systems.
Medicine & Medical Devices
Blood pressure measurement uses millimeters of mercury (mmHg) as the standard unit. Normal blood pressure 120/80 mmHg converts to approximately 16.0/10.7 kPa. Accurate pressure management is also important for medical devices like ventilators and anesthesia machines.
Aerospace Engineering
Aircraft cabin pressure management requires accurate tracking of changes from standard atmospheric pressure. External air pressure at 10,000 meters altitude is about 26 kPa (0.26 bar, 3.77 psi), approximately 1/4 of sea level pressure.
Vacuum Technology
Torr and Pascal (Pa) are used for evaluating vacuum pump and vacuum chamber performance. Unit conversion is needed when handling extremely low pressures like high vacuum (10^-3 Torr) and ultra-high vacuum (10^-9 Torr).
Diving & Underwater Activities
In scuba diving, calculating water pressure at depth is crucial for safety. Water pressure increases by approximately 1 atmosphere (1 atm ≈ 1 bar ≈ 14.7 psi) every 10 meters. For example, at 30 meters depth, total pressure is about 4 atmospheres.
