The megapascal is a x multiple of the pascal unit which is the SI unit for pressure. Primarily used for higher range pressure measurement due to its larger value e. Despite the convenience of using megapascal pressure units to limit the number of digits used on dial gauges and readouts, the bar and the psi pressure unit are still used more commonly used for describing hydraulic pressures. A pressure value in megapascals can be converted into its equivalent value in another pressure unit by multiplying it by one of the factors in the table below. To find the conversion factor to convert to megapascals please click on the appropriate unit below or use our unit converter for multiple calculations if you prefer. Select a look up table for converting a pressure reading in megapascals to other measurement units.

It is also used to quantify internal pressure , stress , Young's modulus , and ultimate tensile strength. The unit of measurement called standard atmosphere atm is defined as , Pa. Reports in the United States typically use inches of mercury [3] or millibars hectopascals. The unit is named after Blaise Pascal , noted for his contributions to hydrodynamics and hydrostatics, and experiments with a barometer. The pascal can be expressed using SI derived units , or alternatively solely SI base units , as:. One pascal is the pressure exerted by a force of magnitude one newton perpendicularly upon an area of one square metre. The unit of measurement called an atmosphere or a standard atmosphere atm is Pa The pascal Pa or kilopascal kPa as a unit of pressure measurement is widely used throughout the world and has largely replaced the pounds per square inch psi unit, except in some countries that still use the imperial measurement system or the US customary system , including the United States. Geophysicists use the gigapascal GPa in measuring or calculating tectonic stresses and pressures within the Earth. Medical elastography measures tissue stiffness non-invasively with ultrasound or magnetic resonance imaging , and often displays the Young's modulus or shear modulus of tissue in kilopascals. In materials science and engineering , the pascal measures the stiffness , tensile strength and compressive strength of materials. In engineering the megapascal MPa is the preferred unit for these uses, because the pascal represents a very small quantity. The pascal is also equivalent to the SI unit of energy density , the joule per cubic metre. This applies not only to the thermodynamics of pressurised gases, but also to the energy density of electric , magnetic , and gravitational fields. The pascal is used to measure sound pressure.

By the same convention, hPa is Pa and kPa is 1, Pa. Pressure can be measured in tons of different units, but the metric, SI unit of pressure is the pascal Pa. One pascal is equal to 1 newton of force per square meter. In laboratories, pressures can vary between orders of magnitude. If you try to achieve a vacuum, your setup may have a pressure of 10 -5 Pa. You may also want to use a pressure vessel with upwards of 10 6 Pa. In materials science, pascals also measure stress, or force per cross-sectional area. In metals, the force per cross-sectional area required to deform a material may be well over 1,,, Pa. To avoid writing all those zeros, we add Greek abbreviations.

Now for those of us who grew up with ounces, pounds, inches, feet and yards, the shift to the metric system makes absolute "logical" sense. This applies not only to the thermodynamics of pressurised gases, but also to the energy density of electric , magnetic , and gravitational fields. Retrieved 4 December Contents Toggle.

I picked a few things of interest and converted from megapascals to psi; I could better grasp their value given my pounds and inches brain.

Loudness is the subjective experience of sound pressure and is measured as a sound pressure level SPL on a logarithmic scale of the sound pressure relative to some reference pressure.
