Pet Medicine Calculator: Tablets to mL

The same prescribed dose arrives in different forms, and converting between them is where errors happen. The calculator starts from the prescribed milligrams — the mg/kg rate times your pet's current weight — then converts into the form you actually have: how many 25 mg tablets a 44 mg dose needs (1.76 tablets — a splitting question), or how many mL of a 50 mg/mL suspension covers 75 mg (1.5 mL). It flags the safety rules: only split scored tablets or plain immediate-release forms, never extended-release or enteric-coated ones, and crush-into-food only with your vet's confirmation that absorption survives food. Worked example: carprofen 2.2 mg/kg for a 20 kg dog is 44 mg — one 25 mg tablet plus three-quarters of another, or cleanly 1.76 mL of the 25 mg/mL suspension.
