To convert between “parts per million” (ppm) and “kilograms per hectare” (kg/ha) requires values for the soil bulk density (in kg/m3) and the depth of the soil layer sampled (in metres). You may choose to use a different values for bulk density like between 900-1500 kg/m3 to convert your values and an average depth of 10cm or
