Dilutions are really simple if you keep track of what’s coming in and what’s coming out. Our dilutions calculator makes it even easier with just three numbers to enter and the result immediately being displayed. The formula behind it is Concentration 1 x Volume 1 = Concentration 2 x Volume 2. You have to choose the right units for it to work so make sure you use the dropdown boxes next to the fields. The missing number (the one you haven’t entered) will apear at the bottom, in the units specified in its dropdown box. Find it useful? Missing a calculator?

I did my PhD in the Department of Chemical Engineering at Imperial College London. My research focused on mathematical modeling of the cell cycle in leukemia and involved experiments with cell lines. During that time, I had to count cells with a hemocytometer so often to track growth that I got tired and decided to build an app, HemocyTap, and share my knowledge on the topic here to help as many people as possible.
