# How do you convert ppm to pressure?

## How do you convert ppm to pressure?

To convert from millimeters of mercury to parts per million (mmHg to ppm), use the formula parts per million (ppm) equals the vapor pressure measured in millimeters of mercury (VP in mmHg) divided by atmospheric pressure in millimeters of mercury (PA in mmHg), then multiply by one million (106).

### What unit is ppm?

parts per million
This is an abbreviation for “parts per million” and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. Seeing ppm or mg/L on a lab report means the same thing.

#### How do you convert ppm to PSI?

By using our Part/Million to PSI/1000 feet conversion tool, you know that one Part/Million is equivalent to 0.000433527504001 PSI/1000 feet. Hence, to convert Part/Million to PSI/1000 feet, we just need to multiply the number by 0.000433527504001.

How do you calculate ppm of gas?

[3] The amount of moles of the concerning gas can be calculated with the molecular weight. For converting ppm by mole, the same equation can be used….Parts per Million by Volume (or mole) in Air.

Vn = specific molar volume of ideal gas (at pressure P and temperature T) [L/mol]
P = pressure [Pa]

How much percent is a ppm?

Percent to ppm conversion table

Percent (%) ppm
0.001% 10 ppm
0.01% 100 ppm
0.1% 1000 ppm
1% 10000 ppm

## What percentage is 2 ppm?

ppm to percent conversion table

ppm Percent (%)
0 ppm 0%
1 ppm 0.0001%
2 ppm 0.0002%
3 ppm 0.0003%

### Why do we use ppm?

ppm (or ppmm) is used to measure the concentration of a contaminant in soils and sediments. In that case 1 ppm equals 1 mg of substance per kg of solid (mg/kg). This use of ppm tends to be phased out in favour of mg/l. ppm (or ppmV) is often used to describe concentrations of contaminants in air (as a volume fraction).

#### Where do we use ppm?

PPM is commonly used in measuring air, water and body fluids pollution. PPM is the mass ratio between a component and a solution.
