Free online pressure converter. Convert between Pascal, bar, psi, atm, mmHg and torr instantly with our easy-to-use tool.
Our free Pressure Converter helps you quickly and accurately convert between all common pressure units used in science, engineering, and everyday life. Whether you're working with tire pressures in psi, weather data in millibars, or scientific measurements in pascals, this calculator handles them all.
Pressure is the force applied per unit area and comes in many different units depending on the field of use. Engineers may work in psi or bar, meteorologists use millibars, and physicists work in pascals. This converter bridges all those worlds so you never have to memorize conversion factors again.
Simply enter a value, select the source and target units, and get an instant, precise result. The tool supports Pascal, bar, psi, atmosphere, mmHg, and torr.
Tracking this metric consistently enables professionals to identify patterns in how they allocate time and effort, revealing opportunities to work more effectively and accomplish more each day. This measurement provides a critical foundation for goal setting and progress tracking, helping you align daily activities with longer-term objectives and meaningful milestones.
This quantitative approach replaces vague time estimates with concrete data, enabling professionals to plan realistic schedules and avoid the pattern of chronic overcommitment. Regular monitoring of this value helps individuals and teams detect productivity patterns and adjust workflows before small inefficiencies become entrenched and hard to correct. Precise quantification supports meaningful goal-setting and accountability, ensuring that improvement efforts are focused on areas with the greatest potential impact on output.
Converted Value = Input Value × (From Unit in Pa) ÷ (To Unit in Pa) Key equivalences: 1 atm = 101,325 Pa = 14.696 psi = 1.01325 bar = 760 mmHg = 760 torr.
Result: 2.4132 bar
35 psi is first converted to Pascal by multiplying by 6,894.76 to get 241,316.6 Pa, then divided by 100,000 Pa/bar to yield approximately 2.4132 bar. This is a common conversion for tire pressures.
Pressure measurement is fundamental across science, medicine, engineering, and everyday life. From checking your tire pressure to monitoring blood pressure, understanding how to convert between units is essential.
The most frequent conversions involve psi and bar for automotive applications, mmHg for medical measurements, and pascals for scientific work. Our converter handles all of these seamlessly, using precise conversion factors referenced to the SI unit pascal.
Pressure plays a critical role in weather forecasting (barometric pressure), healthcare (blood pressure readings in mmHg), scuba diving (atmospheric pressure at depth), industrial processes (hydraulic systems in psi or bar), and aviation (cabin pressure in atm). This converter helps professionals and enthusiasts in all these fields get accurate results without manual calculation.
Bar is a metric unit equal to 100,000 pascals, while psi (pounds per square inch) is an imperial unit. 1 bar is approximately 14.504 psi. Bar is commonly used in Europe and engineering, while psi is standard in the United States.
Multiply the atmosphere value by 14.696 to get psi. For example, 2 atm = 29.392 psi. This conversion is useful when working with pressurized systems or diving calculations.
A pascal (Pa) is the SI unit of pressure, defined as one newton per square meter. It is a very small unit, so kilopascals (kPa) and megapascals (MPa) are more commonly used in practice.
They are essentially the same. Both equal 1/760 of a standard atmosphere. The torr is named after Evangelista Torricelli and is defined as exactly 101,325/760 pascals, which is nearly identical to 1 mmHg.
In the United States, tire pressure is measured in psi. In Europe, bar or kPa are used. A typical car tire pressure is 30–35 psi, which is about 2.07–2.41 bar or 207–241 kPa.
Different fields developed their own units historically. Medicine uses mmHg, weather uses millibars, engineering uses psi or bar, and physics uses pascals. Each unit was convenient for the measurements common in that field.
