Convert pressure from PPM to Pascals
Arguments
- ppm
Pressure value in umol/mol of class units
- P
Atmospheric pressure value in kPa of class units
Value
Value in Pa of class units
Details
$$\mathrm{Press}(kPa) = \mathrm{Press}(ppm) P(kPa)$$
$$\mathrm{Press}(Pa) = 1000 \mathrm{Press}(kPa)$$
Examples
ppm = set_units(400, "umol/mol")
P = set_units(101.325, "kPa")
ppm2pa(ppm, P)
#> 40.53 [Pa]
