Jan 21, Kilopascal Megapascal; 1 kPa: 0. This is simple to use online converter of weights and measures. Simply select the input unit, enter the value and click "Convert" button.

Atmospheric pressure , also known as air pressure or barometric pressure after the barometer , is the pressure within the atmosphere of Earth. The standard atmosphere symbol: atm is a unit of pressure defined as , Pa 1, In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's gravitational acceleration as a function of altitude can be approximated as constant and contributes little to this fall-off.

The unit ppm is used in several branches in different ways. The use of ppm therefore has to be specified in the input fields below, in the way it should convert the value with the proper unit. For more theory about the use of ppm, please see the documentation below. In the input field of Molecular Weight you could either choose from the drop-down list, or you could fill in the value of the molecular weight of the gas. If the molecular weight is unknown to you, please try our Molecular Weight Calculator. The significance is automatically determined. Use extra zero's to expand the significance. In air pollution literature ppm applied to a gas, always means parts per million by volume or by mole. These are identical for an ideal gas, and practically identical for most gases of air pollution interest at 1 atm. Another way of expressing this value is ppmv. Today's more and more there is an interest to express gas concentrations in metric units, i. Additionally, because of difference in molecular weight, comparisons of concentrations of different gases are difficult. The density of gas can be calculated by the Law of Avogadro's, which says: equal volumes of gases, at the same temperature and pressure, contain the same number of molecules.

This effect is strongest in tropical zones, with an amplitude of a few hectopascals, and almost zero in polar areas. For example, 3 kPa multiplied by is equal to MPa. A column of air with a cross-sectional area of 1 in 2 would have a weight of about

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:.

Here is the formula :. Suppose you want to convert 1 kPa into kilograms-force per square meter. Using the conversion formula above, you will get:.

Value to be converted:. Next enter the value you want to convert. From the selection list, choose the unit that corresponds to the value you want to convert, in this case 'Kilopascal [kPa]'. Then, when the result appears, there is still the possibility of rounding it to a specific number of decimal places, whenever it makes sense to do so. With this calculator, it is possible to enter the value to be converted together with the original measurement unit; for example, ' Kilopascal'.

Learn the definition, the conversion process, and the units of pressure. How many Mpa in 1 megapascal? Conversely, Archived 18 June at the Wayback Machine. One pascal is defined as one newton per square meter. In the US weather code remarks, three digits are all that are transmitted; decimal points and the one or two most significant digits are omitted: 1, The pressure in car tires can be in the range of to kPa. In materials science and engineering , the pascal measures the stiffness , tensile strength and compressive strength of materials. Tools Tools. For example, 6 kPa multiplied by 0 is equal to 0. Note that rounding errors may occur, so always …More information from the unit converter. One atmosphere

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. Jan 12, In other projects. If the molecular weight is unknown to you, please try our Molecular Weight Calculator. Maximum potential intensity. SI units. This is where online Master of Public Admin General Conference on Weights and Measures , , p. An important application of the knowledge that atmospheric pressure varies directly with altitude was in determining the height of hills and mountains, thanks to reliable pressure measurement devices. To convert kilopascal to megapascal, multiply the kilopascal value by 0. In other words, 1 kilopascal equal to 0.
