Apa itu?
Pressure is a fundamental physical quantity that measures force applied per unit area. It plays a vital role in numerous fields: automotive mechanics (tire pressure), civil engineering (material strength), meteorology (atmospheric pressure), medicine (blood pressure), and industry (hydraulic and pneumatic systems). Understanding and converting pressure units is essential for every technical professional.

Aplikasi praktikal
Mechanics use PSI ↔ Bar conversion daily for tires and braking systems. Aerospace engineers work with atmospheres (atm) and millimeters of mercury (mmHg) for flight instruments. In medicine, blood pressure is measured in mmHg. HVAC technicians regularly convert between kPa and PSI for air conditioning systems.
Panduan unit
PSI (Pound per Square Inch)
Imperial unit widely used in North America for tire pressure, hydraulic systems, and air compressors.
Bar
Common metric unit in Europe. 1 bar is approximately equal to atmospheric pressure at sea level.
Pascal (Pa)
Official SI unit of pressure. Defined as one Newton per square meter (N/m²). Often used as kPa or MPa.
kPa (Kilopascal)
One thousand Pascals. Standard unit for tire pressure in many countries and for technical specifications.
atm (Atmosphere)
Standard atmospheric pressure at sea level. Universal reference in science and diving.
mmHg (Millimeter of mercury)
Historically linked to mercury barometers. Still the reference in medicine for blood pressure.
Tips praktikal
- 1
Standard atmospheric pressure is 1 atm = 101.325 kPa = 14.696 PSI = 1.01325 Bar.
- 2
Recommended car tire pressure is typically 30-35 PSI (2.0-2.4 Bar).
- 3
Normal blood pressure is approximately 120/80 mmHg.
- 4
Pascal is a very small unit: 1 Pa = 1 N/m². Engineers often use kPa or MPa.
