What this specific question is asking

Ideal Weight Calculator applies one fixed relationship to your inputs. Your part of the work is the inputs: sex and height (cm), each checked for unit and period before entry. Everything else is arithmetic.

Validate by perturbation: nudge sex by ten percent and watch the output. A result that barely moves — or jumps wildly — usually means a wrong unit or period, not a broken formula.

Inputs to verify

Verify sex before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify height (cm) before calculation; if this value uses a different unit, period or definition, convert or restate it first.

Step-by-step check

Select your sex.
Enter your height in centimetres for the formulas.
Press Calculate to see several ideal-weight estimates.
Read them as a range, not a single fixed goal.

Worked example and sanity check

As a worked reference for “How To Check Ideal Body Weight”, Worked example For a 175 cm male (Devine formula): 50 + 2.3 × ((175−152.4)/2.54) = 70.5 kg as a rough reference, not a target.

Interpreting the result

Once the number is in hand, ask what decision it feeds. The example's 70 shows the expected scale for typical inputs. Use your result the same way: as one checked input into the decision, not the whole decision. Treat the number as a screening estimate for orientation, not a diagnosis or a personalised prescription; individual measurement error and physiology dominate any formula's precision.
