Does anyone have any advise on how to convert % dissolved oxygen to mg/l please?

Thanks very much.

You just need to multiply the percentage by 1.33.

ml/L of dissolved oxygen is the equivalent of parts per thousand, which is the same as the percentage. But the volume and mass of gasses are not the same, so ml/L is not the exact same as mg/L

1 PPT (%) = 1.33 mg/L
