Millimeters of Mercury to Pascals Conversion
Converting Millimeters of Mercury (mmHg) to Pascals (Pa) is a common pressure conversion. 1 mmHg equals 133.322 Pa. For example, 100 mmHg is equal to 13,332.2 Pa.
Quick Mental Math: Millimeters of Mercury to Pascals
Multiply millimeters-of-mercury by approximately 133.32 to convert to pascals.
Why is converting Millimeters of Mercury to Pascals tricky?
The non-integer multiplier 133.32 is imprecise for mental estimation.
Quick Reference Values
1 mmHg = 133.322 Pa. 5 mmHg = 666.61 Pa. 10 mmHg = 1,333.22 Pa. 25 mmHg = 3,333.05 Pa. 50 mmHg = 6,666.1 Pa. 100 mmHg = 13,332.2 Pa.
What is Millimeters of Mercury?
Millimeters of Mercury (mmHg) is a unit of pressure. Millimeters of mercury (mmHg) measure pressure based on a column of mercury 1 millimeter high. It equals exactly 133.322387415 pascals, the SI derived unit for pressure, as defined by international standards. This unit is widely used in medical and meteorological fields for blood pressure and barometric pressure readings [nist-si-guide]. The mmHg unit originated from the mercury barometer invented by Evangelista Torricelli in 1643. It became standardized as a pressure unit because mercury's density allowed precise atmospheric pressure measurements. The adoption of the exact pascal conversion was formalized by the BIPM in the 20th century [bipm-si-brochure]. Millimeters of mercury remain common in healthcare worldwide, especially for blood pressure monitoring in the US and Europe. Meteorologists also use mmHg in weather reporting, though pascals are preferred in scientific contexts. Regulatory standards by ISO and NIST recognize mmHg for specific applications [nist-sp-811].
What is Pascals?
Pascals (Pa) is a unit of pressure. The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter (1 Pa = 1 N/m²). It quantifies force applied evenly over an area and is expressed as kg·m⁻¹·s⁻² in base SI units [bipm-si-brochure]. Named after Blaise Pascal, the pascal was adopted by BIPM in 1971 to replace older pressure units and standardize measurement in the SI system. It reflects the link between force and area in pressure measurements [bipm-si-brochure]. Pascals are the standard pressure unit in scientific research, meteorology, and engineering globally. Countries following SI, including members of ISO and NIST guidelines, use pascals for atmospheric and mechanical pressure [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: millimeter of mercury, mm hg, millimeters mercury, mmhg, millimeters of mercery, pascal, pascals, pascel, pascall, pasceles. All of these refer to the Millimeters of Mercury to Pascals conversion.
