Devine Ideal Weight Calculator
The calculator estimates weight with the Devine formula from height and sex. At 175 cm and male the result is 70.5 kg. At 165 cm and female it is 56.9 kg. That is a dosing formula, not a “perfect body.”

Not a clinic verdict and not a physique target. Devine estimates mass for doses. Lorentz lives on ideal body weight.
How it works
Ideal weight (Devine) in this calculator is a mass from height and sex. Height in cm becomes inches: hIn = cm / 2.54. Male: 50 + 2.3 × max(0, hIn − 60). Female: 45.5 + 2.3 × the same. 175 cm and male give 70.5 kg. The calculator rounds to 0.1 kg and appends kg.
165 cm and female give 56.9 kg. 180 cm and male give 75.0 kg. Below 60 in (152.4 cm) the 2.3 term drops and you keep 50 kg or 45.5 kg. This is not the BMI 18.5 to 24.9 band.
The height field is height. Sex is a list M or K. K is female, not F. Current mass, age, and activity do not enter 70.5 kg. They only compute a delta, BMI at that mass, and a BMR estimate when you fill them.
Lorentz at 175 cm and male gives 68.8 kg on ideal body weight. Here Devine gives 70.5 kg from another formula. Neither number is the “right body”.
Enter height, pick sex, then Calculate. A comma in 175.5 parses. Zero height leaves a blank. A dosing estimate, not a diet and not a doctor order.
175 cm and male give 70.5 kg. 165 cm and female give 56.9 kg. 180 cm and male give 75.0 kg. With a US header, height is in inches and the result can be lb.
male: 50 + 2.3 × max(0, hIn − 60); female: 45.5 + 2.3 × max(0, hIn − 60); hIn = cm / 2.54
Devine from inches. 175 cm and male give 70.5 kg. 165 cm and female give 56.9 kg. Dosing, not a physique.

Common questions
What Devine weight at 175 cm and male?
70.5 kg. hIn = 175/2.54, then 50 + 2.3 × (hIn − 60), rounded to 0.1.
What about 165 cm and female?
56.9 kg. Base 45.5 instead of 50. The sex value is K.
What about 180 cm and male?
75.0 kg. The same formula, a taller height.
Is 70.5 kg an ideal body?
No. Devine is from dosing. Not a physique target and not a clinic verdict.
How is this different from ideal body weight?
There, Lorentz. 175 cm and male give 68.8 kg. Here Devine gives 70.5 kg.
Does current mass change 70.5 kg?
No. It only computes a delta and BMI at that mass. Devine itself uses height and sex.
What if height is below 152.4 cm?
hIn minus 60 is negative, so max leaves 0. Male gets 50 kg, female 45.5 kg.
Does a comma in 175.5 work?
Yes. 175.5 and 175,5 are the same height.
Does a US header change the result?
Yes. Then the field is inches, and fmtMassKg can show lb. The 70.5 kg examples are metric.
How do I calculate ideal weight with Devine?
Convert height to inches (cm / 2.54). Male: 50 + 2.3 × (inches − 60). Female: 45.5 + 2.3 × (inches − 60). At 175 cm and male the result is 70.5 kg.
Is the Devine result a body-composition goal?
No. The formula came from dosing practice. It ignores muscle mass and frame size and does not replace clinical advice.
How is Devine different from Lorentz?
On the ideal-weight page Lorentz at 175 cm and male gives 68.8 kg. Here Devine gives 70.5 kg from the same height and sex.
What happens below 152.4 cm height?
Inches minus 60 go negative, so the model keeps 0 in that term. Males get the 50 kg base, females 45.5 kg.
