grains

grains calculates the amount of water you need for your grains. So far, you can do this for couscous, quinoa & rice. Just enter the quantity and the units (either "g" or "cups"). I am going to add more grains.

You can install:

if (packageVersion("devtools") < 1.6) {
        install.packages("devtools")
}

devtools::install_github("elhumble/grains")

For example

If you want to know how much water you need for 50g of couscous:

library(grains)
couscous(50, "g")
#> For 50 g of couscous you need 125 ml of water
