[h=1]How to calculate TDS and convert to PPM?[/h]So I collected 20mls of late water,
and in the end the solid remains (unknown) is 5gs.
How do i convert my answer to PPM, since the units for TDS is ppm?

Convert to mg/L

5 grams = 5 x 10^3 mg = 5000 mg

20ml = 20 x 10^-3 L = 0.02 L

5000mg / 0.02 L
250000mg/L
