Tentang Konverter tekanan

Each pressure unit is a fixed number of pascals (newtons per square metre). The bar is exactly 100,000 Pa, the standard atmosphere 101,325 Pa and the torr 1/760 atm. The psi, one pound-force per square inch, is about 6,894.757 Pa, fixed exactly by the 1959 pound, standard gravity (9.80665 m/s²) and the 25.4 mm inch.

The default converts a 32 psi tyre pressure to 2.2063 bar. Weather maps use hectopascals (1 hPa = 1 mbar; standard sea-level pressure is 1,013.25 hPa), and blood pressure is recorded in millimetres of mercury.

Gauge and absolute readings convert with the same factor but are not interchangeable: a tyre gauge shows pressure above the surrounding air, so 32 psi on the gauge is about 46.7 psi absolute at sea level. The inch of mercury uses the conventional value at 0 °C and is marked approximate.

Pertanyaan

How do I convert psi to bar?

Divide by 14.5038, or multiply by 0.0689476. A bar is 100,000 Pa and a psi 6,894.757 Pa, so 1 bar = 14.5038 psi. A 32 psi tyre is 2.2063 bar, and a 2.5 bar tyre is 36.26 psi.

Is 1 bar the same as 1 atmosphere?

No, though they are within 1.3%. The bar is exactly 100,000 Pa, while the standard atmosphere is exactly 101,325 Pa, which is 1.01325 bar, 14.696 psi or 760 mmHg. The atmosphere was set to match average sea-level air pressure, which is why weather charts centre on 1,013.25 hPa.

What is the difference between psig and psia?

psig is gauge pressure, measured relative to the surrounding air; psia is absolute pressure, measured from a vacuum. At sea level psia = psig + 14.696. Tyre and compressor gauges read psig, so a flat tyre shows 0 psig while still holding 14.7 psia of air. The converter treats both alike, so keep input and output the same kind.

Are mmHg and torr the same?

Almost. A torr is exactly 1/760 of a standard atmosphere, 133.322368 Pa, while the conventional millimetre of mercury is 133.322387415 Pa; they differ by about 0.14 parts per million. For blood pressure the difference never matters: 120/80 mmHg is 16.0/10.7 kPa either way.

How do I convert inches of mercury to hPa?

Multiply by 33.8639: 29.92 inHg is 1,013.2 hPa, the standard altimeter setting in US aviation. This converter uses the conventional inch of mercury at 0 °C, 3,386.389 Pa (NIST SP 811), and marks results that use it as approximate because mercury's density changes with temperature.

Seberapa akurat “Konverter tekanan”?

Akurasi bergantung pada masukan dan asumsi metode. Aritmetika desimal memakai 50 digit signifikan, tetapi perkiraan, metode numerik dan data sumber bisa kurang presisi; pembulatan yang ditampilkan tidak menghilangkan batasan itu. Contoh penyelesaian yang diperiksa dengan sumber independen: 4. Misalnya, “32 psi tyre pressure in bar” diperiksa dengan 1 psi = 4.4482216152605 N ÷ (0.0254 m)² (NIST SP 811 App. B); 32 psi = 8896443230521/4032250000000 bar (Python 3.8 fractions from the legal definitions).
