Question 1

Which formula is the most accurate?

Accepted Answer

No single formula is universally accurate. The Devine formula is the most commonly used in clinical settings, but all four formulas are estimates and do not account for muscle mass, age, or body composition.

Question 2

Does it work in imperial units?

Accepted Answer

Yes. Switch to Imperial mode and enter your height in feet and inches.

Question 3

Why is there a minimum height of 60 cm?

Accepted Answer

The formulas are designed for adults and are based on height above 60 inches (about 152 cm). Results below that threshold are not medically meaningful.

Question 4

What is ideal body weight?

Accepted Answer

Ideal body weight (IBW) is an estimate of the weight considered healthiest for a person of a given height and sex, based on clinical formulas developed for use in medical settings such as drug dosage calculations.

Question 5

Should I use ideal weight as a health goal?

Accepted Answer

Ideal weight formulas are rough estimates and should not be treated as strict targets. Consult a healthcare professional for personalised advice, as factors like muscle mass, age, and body composition all influence what a healthy weight is for you.
