Pascals to Inches of Mercury Conversion
Converting Pascals (Pa) to Inches of Mercury (inHg) is a common pressure conversion. 1 Pa equals 0.000295 inHg. For example, 100 Pa is equal to 0.02953 inHg.
Quick Mental Math: Pascals to Inches of Mercury
Divide pascals by approximately 3386.39 to convert to inches-of-mercury.
Why is converting Pascals to Inches of Mercury tricky?
The non-integer divisor 3386.39 requires careful mental arithmetic.
Quick Reference Values
1 Pa = 0.000295 inHg. 5 Pa = 0.001476 inHg. 10 Pa = 0.002953 inHg. 25 Pa = 0.007382 inHg. 50 Pa = 0.014765 inHg. 100 Pa = 0.02953 inHg.
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].
What is Inches of Mercury?
Inches of Mercury (inHg) is a unit of pressure. Inches of mercury measure pressure as the height of a mercury column in inches exerted by atmospheric or other pressures. One inch of mercury equals exactly 3,386.389 pascals (Pa). This unit is commonly used in barometry and aviation altimetry [nist-si-guide]. The unit originates from mercury barometers developed by Evangelista Torricelli in 1643. Measuring pressure via mercury column height became standard in meteorology and aviation. The inch unit was adapted for use in English-speaking countries [nist-si-guide]. Inches of mercury are used mainly in the United States and Canada for weather reports and aircraft altimeters. Internationally, the pascal is preferred, but inHg remains common in aviation and HVAC industries [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: pascal, pascals, pascel, pascall, pasceles, inch of mercury, inch-mercury, in hg, inches mercury. All of these refer to the Pascals to Inches of Mercury conversion.
