Concentration Converters
22 conversion pages for concentration units, each with its exact factor, the formula and a reference table.
The Concentration Converters collection covers 22 pages of concentration units — one page for each ordered pair of units, so there is nothing to configure before you get an answer.
There is one page per direction. A dual-dropdown converter is fewer pages but a worse answer: the examples, the reference table and the rounding advice on “Micromoles Per Liter to Millimoles Per Liter” are all specific to that pairing, and none of it survives being made generic.
The pages are built to be useful without any typing: the formula is written out, the multiplication is shown step by step, and a reference table covers the values people actually look up, so a glance is often enough. Type your own figure in and the result updates as you go, entirely in your browser.
This collection reaches across molarity, millimolar and moles per cubic metre. Sitting in Science & Lab Units, it links back to the sibling collections that share its units, so a chain of conversions never needs a second tab.
