Those calculators seem pretty handy:

How about we hunt down some more calculators like:
TDS to μS (microSiemens) Rough estimate
TDS in ppm multiplied by 1.5 gives conductivity in μS/cm for tapwater at room temperature.
Carbonate Hardness ppm to kH german degrees (divide by 17.85)
And same for General Hardness.
Great calculator here:

http://www.aquaticcommunity.com/converter/hardness-calculator.php
Basic tank volume calculator
Maybe a ph scale and some nitrates/nitrites/ammonium/phosphate calcs.
There's loads more. What else do you think would be good?:dk:
