ກ່ຽວກັບເຄື່ອງຄິດໄລ່ນີ້
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.
ຄໍາຖາມທີ່ຖາມເລື້ອຍໆ
ບາມີແຮງດັນເທົ່າໃດ?
ບາຫນຶ່ງເທົ່າກັບປະມານ 14.5038 psi. ບາແມ່ນໃກ້ກັບບວກຫນຶ່ງ, ດັ່ງນັ້ນຄວາມກົດດັນລົດຖີບໃນບາແລະ psi ແມ່ນປະມານ 1-to-14.5 ອັດຕາສ່ວນ.
ຊັ້ນບັນຍາກາດແມ່ນຫຍັງ?
1 ມາດຕະຖານບວກ (atm) ແມ່ນ 101,325 pascals, ປະມານ 1.013 ບາຫຼື 14.696 psi. ມັນແມ່ນຄວາມກົດດັນອາກາດສະເລ່ຍທີ່ລະດັບທະເລ.
ຫຍັງຄື mmHg ຖືກນໍາໃຊ້ສໍາລັບ?
Millimeters of mercury measure blood pressure and barometric pressure. One mmHg is about 133.322 pascals, and 760 mmHg equals one atmosphere.
ວິທີການທີ່ຂ້ອຍຈະປ່ຽນ psi ເປັນບາ?
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.
ມີຄວາມແຕກຕ່າງກັນລະຫວ່າງ torr ແລະ mmHg ແມ່ນຫຍັງ?
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.
ມิลລີບີຣ ແມ່ນຫຍັງ ແລະ ຖືກໃຊ້ຢູ່ໃສ?
A millibar is one-thousandth of a bar, or 100 pascals, and is the traditional unit for atmospheric pressure in weather reports. Standard sea-level pressure is about 1,013 mbar.
