Why several formulas are shown
Devine, Robinson, Miller, and Hamwi use different constants, so they can return noticeably different values for the same height.
Not a health target
These equations are historical reference formulas, not a diagnosis or personalized recommendation. They ignore body composition, health conditions, age-related changes, ethnicity, pregnancy, and individual goals.
How to interpret the output
Treat the range as a comparison of formulas only. A qualified healthcare professional can evaluate weight and health using much broader information.
