First you need to find the height of a column of water of area 1 m^2 and mass 1 kg. Since the density of liquid water is ~1000 kg/m^3, the height of the column must be 0.001 m, or 1 mm. Numerically, the "conversion" from kg/m^2 to mm of liquid water is 1. To convert the precip rate to mm/day, multiply by 86400. To get it in mm/month, multiply by the number of days in the month you're interested in.
