मिलीमीटर का Water (4°C)
Millimetre of water at 4°C (mmH₂O) की एक मात्रक है pressure के बराबर लगभग 9.80638 pascals, defined as the pressure exerted by a one-millimetre column of water at 4°C. It is used in low-pressure measurement applications including HVAC systems, medical ventilators, and draft pressure gauges. One mmH₂O equals one-tenth of a cmH₂O.
पास्कल
The pascal (Pa) SI की व्युत्पन्न मात्रक है pressure, defined as one newton per वर्ग मीटर (N/m²). It was adopted by the General Conference on Weights and Measures in 1971 and के नाम पर the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure लगभग है 101,325 Pa, and it is widely used in science, engineering, and meteorology.
