A pond is a measure of mass whereas psi is a measure of pressure. The two measure different attributes and, according to very basic dimensional analysis, any attempt to convert one to the other is flawed. Multiply psi by 0.In a hydraulic system, it is often beneficial to not only display the pressure in the system but to also display the force being exerted by a hydraulic ram. This could be simply to display the actual force being exerted by a hydraulic ram in a familiar format.

APG gauges are able to display the pressure readings in a few industry-standard units as well as many other units for force by using a simple conversion factor or multiplier.

## Convert lbs to psi - Conversion of Measurement Units

The principle behind the process is a simple conversion from one unit to another; in this case the APG digital pressure gauge can convert PSI to lbs.

The trick to understanding how this conversion works is to break it down into its base units. PSI is a unit of measure for pressure, and pressure PSI is the amount of force lbf applied per unit of area in2. The equations below illustrate this. To convert PSI to lbs, simply multiply the pressure by the area over which the force is applied.

Years ago, a motorcycle design and manufacturing company approached us about using one of our psi PG7 Digital Pressure Gauges to measure lbs of force from a hydraulic ram.

Lbs of force, however, is not a unit of pressure displayed by our gauge; therefore, the custom unit converter function that is built into all of our gauges needed to be used.

Then, the multiplier for converting psi to lbs needs to be determined, using the area where the force is applied. The manufacturer of the hydraulic ram will sometimes provide the area. When not provided, the area will need to be calculated. To set the gauge to display in lbs, simply use the area It is important to note, however, that depending on the maximum pressure of your gauge, the measurement might be too long to fit on the 4-digit digital display of the pressure sensors.

You will need to do some quick math to ensure the maximum measurement will fit on the pressure sensors display. To do this, we multiple the maximum PSI of the digital pressure gauge by the previously calculated area.

In our example with the motorcycle company, we would multiply the maximum output of the PG7 PSI by the area of the hydraulic ram To determine the scale factor for tons, we convert the full-scale psi pounds of force per square inch to full-scale pounds. To convert this to tons, we will divide 98,by lbs, or one ton, to get 49 tons.

So, when our hydraulic ram is pressing down to full-scale measurement on our psi gauge, we want it to display 49 tons.

To get the multiplier that you'll enter into the gauge to display tons, divide the tons calculated above 49 by the psi full scale This equals 0. You can now move on to the programming steps. Once you have determined the correct multiplier for your gauge and application you can set up the gauge to display the desired units. Step 5: Press Select to access the Custom Units setting.

You can also contact us directly if you find any missing units or errors. The pound abbreviation: lb is a unit of mass or weight in a number of different systems, including English units, Imperial units, and United States customary units. Its size can vary from system to system. The most commonly used pound today is the international avoirdupois pound. The international avoirdupois pound is equal to exactly The definition of the international pound was agreed by the United States and countries of the Commonwealth of Nations in In the United Kingdom, the use of the international pound was implemented in the Weights and Measures Act An avoirdupois pound is equal to 16 avoirdupois ounces and to exactly 7, grains.

It is the pressure resulting from a force of one pound-force applied to an area of one square inch. You can find metric conversion tables for SI units, as well as English units, currency, and other data.

Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. Examples include mm, inch, kg, US fluid ounce, 6'3", 10 stone 4, cubic cm, metres squared, grams, moles, feet per second, and many more!Please provide values below to convert psi [psi] to bar, or vice versa. Definition: A pound-force per square inch symbol: psi is an imperial and US customary unit of pressure based on avoirdupois units.

It is defined as the pressure that results when a force of one pound-force is applied to a one-square-inch area. It is based on the avoirdupois system, a system that uses weights in terms of the avoirdupois pound, which was standardized in The system is believed to have come into use in England around and was used in the international wool trade. As such, the prototype pound at the time was known as the avoirdupois wool pound.

Current use: The psi is fairly widely used to measure numerous pressures, such as tire pressure, scuba tank pressure, natural gas pipeline pressure, among others. Although the pascal is more widely used in scientific contexts, psi is more often used in everyday contexts, particularly in countries like the United States as well as others under the US customary or imperial systems of units. Definition: A bar symbol: bar is a metric unit of pressure that is defined as exactlypascals symbol: Pa. It is equal to 0.

### Psi to Pound/Square Inch Conversion

The term "bar" comes from the Greek word "baros," which means weight. Current use: Although the bar is a metric unit of pressure, it is not accepted within the International System of Units SI and is even deprecated within certain fields.

The International Bureau of Weights and Measures has specified the bar as a unit that authors should have the freedom to use but has chosen not to include the bar in the list of non-SI units accepted for use with SI. Millibars symbol: mb are also commonly used when referencing atmospheric air pressure, where atmospheric pressure equals Meteorologists and weather reporters worldwide often use this unit for convenience, since working in pascals would result in much larger values.

From: psi To: bar.Where P is equal to pressure, F is the normal force and A is area. Since pressure is derived from force and area, many units for pressure directly relate force to area. Some are obvious, such as pounds per square inch, but even the SI standard Pascal is actually an expression of one Newton per square meter.

Conversions are performed by using a conversion factor. By knowing the conversion factor, converting between units can become a simple multiplication problem:. Where S is our starting value, C is our conversion factor, and E is our end converted result. To simply convert from any unit into pascalsfor example, from 5 bar, just multiply by the conversion value in the right column in the table below.

To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into Pascals then divide by the factor for B to convert out of Pascals.

Or, you can find the single factor you need by dividing the A factor by the B factor. So, to convert directly from bar to pounds per square inch, you multiply by Lide, David R. Wikipedia contributors. Wikipedia, The Free Encyclopedia, last visited 26 Jun.

Pounds per square inch absolute psia is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around The converse is pounds per square inch gauge psigindicating that the pressure is relative to atmospheric pressure. They are mostly used in materials sciencewhere the tensile strength of a material is measured as a large number of psi. The megapound per square inch Mpsi is another multiple equal to a million psi.

It is used in mechanics for the elastic modulus of materials, especially for metals. The conversions to and from SI are computed from exact definitions but result in an inexact number that must be rounded at some point. As the pascal is very small unit, relative to industrial pressures, the kilopascal is commonly used. From Wikipedia, the free encyclopedia. Unit of pressure or stress.
