Pressure measures force applied perpendicular to a surface per unit area. From the atmospheric pressure that affects weather to the hydraulic pressure that powers machinery, understanding pressure is fundamental to many fields. Our converter handles scientific units (pascals), industrial units (bar, psi), and specialized units (mmHg for medicine, atmospheres for diving).
The scientific study of pressure began with Evangelista Torricelli's invention of the mercury barometer in 1643. Blaise Pascal further developed pressure theory, leading to the naming of the SI unit in his honor. The concept of atmospheric pressure revolutionized our understanding of weather and led to practical applications from barometers to vacuum pumps.
Multiply pressure in bar by 14.5038 to get pounds per square inch.
Example: 2 bar × 14.5038 = 29.01 psi
Multiply psi by 6.89476 to get kilopascals.
Example: 35 psi × 6.89476 = 241.3 kPa
Multiply atmospheres by 101,325 to get pascals.
Example: 1 atm × 101,325 = 101,325 Pa
Multiply mmHg by 0.133322 to convert to kilopascals.
Example: 760 mmHg × 0.133322 = 101.3 kPa
Typical passenger car tire pressure is around 32 psi (220 kPa).
Healthy blood pressure is typically around 120/80 mmHg systolic/diastolic.
At 10 meters underwater, pressure increases by approximately 1 atmosphere.
Espresso is typically brewed at 9 bar of pressure.
Standard atmospheric pressure at sea level.
A typical pressure cooker operates at about 15 psi above atmospheric.
