Let me differentiate first between design pressure and mechanical design pressure. Design (or discharge) pressure is the pressure at the outlet of the pump, the pressure you've designed the pump to deliver. The mechanical design pressure is a value that the pump casing and downstream piping have to be able to withstand as a minimum*. I presume you mean design pressure as discharge pressure. In this case, differential pressure is the difference between the discharge pressure and the suction pressure (the pressure at the inlet of the pump**). * this is calculated taking into account that a pump would be working against a 'blocked discharge' or a closed valve in the outlet piping ** imagine a reservoir filled with liquid
It is not possible to convert kilograms (mass) directly to pounds per square inch (pressure) as they are different units. To convert mass to pressure, you would need additional information such as the area over which the force is applied.
It doesn't make sense to convert units that measure completely different things. You can only convert units of length to units of length, units of mass to units of mass, etc.
To convert barometer pressure from metric to imperial, multiply the metric value by 0.02953. For example, if the pressure is 1013 hPa, the conversion to imperial units would be 1013 x 0.02953 = 29.93 inHg.
You use conversion factors.
To convert MPa units to psi units, you can use the conversion factor: 1 MPa = 145.038 psi. Simply multiply the pressure in MPa by 145.038 to obtain the pressure in psi.
You can't convert from units of pressure to units of mass. It just doesn't make sense.
Absolute vacuum refers to a theoretical state where there is a complete absence of matter, including particles and radiation. It is a state with zero pressure and zero energy. This concept is used in physics to establish a benchmark for comparing different pressure levels in a system.
A unit of absolute pressure in the metric.ATA(s): Abbreviation for "Atmospheres Absolute", defines as the total pressure exerted on an object, by a gas or mixture of gases, at a specific depth or elevation, including normal atmospheric pressure.
No common vacuum units that I know of use negative values for a vacuum. Although pressure is an absolute quantity, everyday pressure measurements, such as for tire pressure, are usually made relative to ambient air pressure. In other cases measurements are made relative to a vacuum or to some other ad hoc reference. When distinguishing between these zero references, the following terms are used: Absolute pressure is zero referenced against a perfect vacuum, so it is equal to gauge pressure plus atmospheric pressure. Gauge pressure is zero referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure. Negative signs are usually omitted. Differential pressure is the difference in pressure between two points. The zero reference in use is usually implied by context, and these words are only added when clarification is needed. Tire pressure and blood pressure are gauge pressures by convention, while atmospheric pressures, deep vacuum pressures, and altimeter pressures must be absolute. Differential pressures are commonly used in industrial process systems. Differential pressure gauges have two inlet ports, each connected to one of the volumes whose pressure is to be monitored. In effect, such a gauge performs the mathematical operation of subtraction through mechanical means, obviating the need for an operator or control system to watch two separate gauges and determine the difference in readings. Moderate vacuum pressures are often ambiguous, as they may represent absolute pressure or gauge pressure without a negative sign. Thus a vacuum of 26 inHg gauge is equivalent to an absolute pressure of 30 inHg (typical atmospheric pressure) − 26 inHg = 4 inHg.
One foot of water at 4 degrees Celsius is equivalent to 816.2 feet of air at 15 degrees C.
Depends, what you want to convert to what. To convert between different metric units, powers of 10 are used. For example, a kilometer is 1000 meters. To convert from metric units to imperial units, you have to ask specific questions for specific units, for example, "how to convert inches to meters", or "how to convert pounds to kilograms".Depends, what you want to convert to what.

It doesn't make sense to convert that. You can only convert units of the same kind, e.g., units of length to units of length; units of area to units of area; units of time to units of time, etc.

You can't convert that. You can convert linear units to linear units, square units to square units, or cubic units to cubic units.
You would add "psia" (pounds per square inch absolute) to Boyle's Law when you are dealing with pressure measurements that are already in absolute pressure units, such as when working with a sealed container or a vacuum system. Boyle's Law describes the relationship between pressure and volume when temperature is held constant.
