Questions
How do I convert psi to bar for my tyres?
1 bar = 14.5038 psi, so divide psi by 14.5. A car tyre at 32 psi is about 2.2 bar (220 kPa). Always use the pressure printed on your vehicle’s door frame or manual.
What does 120/80 mmHg mean?
Blood pressure is measured in millimetres of mercury. 120 mmHg ≈ 16 kPa; 1 mmHg = 133.322 Pa.
Is kgf/cm² the same as bar?
Nearly: 1 kgf/cm² = 0.980665 bar. Older Indian gauges, pumps and pressure cookers often show kgf/cm².
