Pets Calculators

Our pet calculators help you provide the best care for your furry, feathered, or finned friends. Whether you need to convert your dog's age to human years, calculate daily calorie needs, or determine if that chocolate your pup got into is dangerous, we've got you covered.

Dog owners can use our comprehensive suite of canine calculators including age conversion using modern formulas (not the outdated "multiply by 7" myth), calorie calculators based on the RER formula used by veterinary nutritionists, pregnancy due date calculators, and the critically important chocolate toxicity calculator.

Cat parents can accurately convert their feline's age to human years, understanding that cats mature quickly in their first two years before aging more gradually.

Aquarium enthusiasts can calculate tank volume for proper fish stocking and medication dosing, plus estimate the total weight of a filled tank to ensure proper floor support.
