Reconstitution Calculator runs on your own machine — the client starts it, so there is no endpoint to ping. 48 installs a week from npm.
Lab math: reconstitution, unit conversion, C1V1, molarity, percent w/v, serial dilution.
Today is the operative word: we check Reconstitution Calculator every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
