Perihal kalkulator ini
A pressure converter changes a pressure reading between pascals and kilopascals, bar and millibar, the standard atmosphere, psi, and the mmHg, torr and inHg units used in weather, medicine and vacuum work. All values convert through the pascal as a common base.
The reference points worth memorising are 1 atm = 101,325 Pa = 1.01325 bar ≈ 14.696 psi = 760 mmHg. A bar is very close to one atmosphere, and one psi is about 6,895 pascals, which is why tyre and industrial pressures move between bar and psi in a roughly 1-to-14.5 ratio.
Worked example: to convert 2 bar to psi, multiply by 14.5038, giving about 29.0 psi — a typical car tyre pressure. To convert a 120 mmHg blood-pressure reading to kilopascals, multiply by 0.133322, giving about 16.0 kPa. A results table shows the same pressure in every unit at once.
Pertanyaan yang kerap ditanya
Berapa banyak psi dalam bar?
One bar equals about 14.5038 psi. A bar is close to one atmosphere, so car tyre pressures in bar and psi are roughly a 1-to-14.5 ratio.
Apa itu satu atmosfera?
One standard atmosphere (atm) is 101,325 pascals, about 1.013 bar or 14.696 psi. It is the average air pressure at sea level.
Apa yang mmHg digunakan untuk?
Millimeters of mercury measure blood pressure and barometric pressure. One mmHg is about 133.322 pascals, and 760 mmHg equals one atmosphere.
Bagaimana saya menukar psi kepada bar?
Divide psi by 14.5038, or multiply by 0.0689476. So 32 psi (a common tyre pressure) is about 2.2 bar. This pressure converter uses the exact factor of 6,894.76 pascals per psi.
Apa perbezaan antara torr dan mmHg?
They are practically identical: one torr is defined as 1/760 of an atmosphere and one mmHg is about 133.322 pascals, differing only in the seventh significant figure. For everyday purposes they are interchangeable.
Apa itu milibar dan di mana ia digunakan?
Milibar adalah satu-ribuan bar, atau 100 pascal, dan adalah unit tradisional untuk tekanan atmosfer dalam laporan cuaca. Tekanan paras laut piawai adalah sekitar 1,013 mbar.
