Not medical advice
The body mass index and energy pages are screening estimates for adults. They are not a diagnosis, not a measurement of body fat, and not a diet or treatment plan. Pregnancy, illness, sport, and many medicines change what a healthy range means. Talk to a qualified clinician about your own health.
Not financial, tax, or legal advice
Interest, loan, discount, and tip results are arithmetic illustrations. They are not a loan offer, not tax advice, and not a recommendation to save, borrow, or spend. Real products can include fees, insurance, taxes, and rate changes that these pages omit.
Estimates
Activity multipliers, rounded money, and calendar conventions are stated on each page. A different convention, including the treatment of 29 February, can change a result. Check the worked example if you need to see which rule the page uses.
