Frequently Asked Questions
Devine vs Robinson — which?
Both estimate from height: Devine (1974, classic clinical) and Robinson (1983, slightly adjusted). The tool shows both: a 170 cm man reads Devine 65.9 kg and Robinson 65.2 kg. Only heights above 100 cm compute.
Is this my exact right weight?
No — formulas ignore frame, muscle, and age. Athletes and older adults fall outside formula bands normally; treat output as a starting reference.
Should I set goals from this range?
No — informational only. Weight goals involving health conditions deserve a doctor or dietitian, not a formula.
Does my height data leave the browser?
No — math runs locally in your browser. Health data never leaves your device.
