In nicholascarey/respfun: Collection of useful functions for respirometry data and experiments

Convert a mass of water to a volume

Description

wm_to_vol converts a water mass to a water volume. Requires temperature, salinity and atmospheric pressure. These are used to calculate the density, which is then used to convert the mass to volume.

Usage

wm_to_vol(mass, t, S, P)

Arguments

mass	numeric (kg). Water mass to convert to volume
t	numeric (°C). Temperature
S	numeric (ppt). Salinity
P	numeric (bar). Atmospheric pressure. Defaults to 1.013253

Inputs

Inputs must be in SI units:

• mass in kg

• t in °C

• S in ppt

• P in bar (Defaults to 1.013253)

Output

Output is a single numeric value for the water volume in L.
