Health calculators

BMI, pregnancy and ovulation tools use standard published methods applied to the inputs you provide. They cannot diagnose anything, replace a clinician, or guarantee outcomes. Individual cycles, bodies and pregnancies vary.

Pet age calculators

Dog and cat age conversions are approximations based on published research and veterinary conventions. They vary significantly by individual animal, breed and size.

Financial calculators

Loan, savings and investment projections are pure arithmetic. They do not predict markets, include taxes or fees, or constitute financial advice. Currency conversion uses an hourly public reference feed with daily fallbacks, not tradeable quotes.

General

If accuracy matters for a decision that affects safety, money or health, verify important results independently.
