Incomplete conversion between imperial and metric units
In one recipe (Breakfast Oats Jar) originally using imperial units I'm now asked to add "157 11/15 ml" of milk which seems excessively exact. Also using a fraction is absolutely unusual in a non-imperial setting. The smallest fraction I would expect here is "1/8" and even that is less and less common. A great thing would be some kind of "intelligent rounding" flag in the settings (in this case probably to "160 ml"). Or the recipes themselves could support dual units so that the values are somewhat reviewed.
Also, the amount of berries (6 oz) is not converted at all.
