Formula & Mathematical Methodology: Waist-to-Height (WHtR) & ABSI Formula

WHtR = Waistcm / Heightcm
ABSI = Waistm / [ BMI2/3 × Heightm1/2 ]
WHtR = Waist_cm / Height_cm; ABSI = Waist_m / [ BMI^(2/3) × Height_m^(1/2) ]
  • waistCircumferenceCm: Waist Circumference Cm (cm)
  • standingHeightCm: Standing Height Cm (cm)
  • bodyWeightKg: Body Weight Kg (kg)

Rounding: Clinical scores round to statutory integer or decimal precision; physiological metrics round to 2 decimal places.

Worked Example: Clinical / Physiology Scenario: Waist-to-Height (WHtR) & ABSI

Assess central visceral adiposity via Waist-to-Height Ratio (<0.50), BRI, and ABSI.

  1. Enter lab values, anthropometric measurements, or performance test metrics.
  2. Evaluate the reference equation: WHtR = Waist_cm / Height_cm; ABSI = Waist_m / [ BMI^(2/3) × Height_m^(1/2) ].
  3. Inspect the primary classification, supporting indices, and 3 SVG charts.
Result: Computes Waist-to-Height (WHtR) & ABSI via WHtR = Waist_cm / Height_cm; ABSI = Waist_m / [ BMI^(2/3) × Height_m^(1/2) ].

Frequently Asked Questions

How does the Waist-to-Height Ratio (WHtR), Conicity Index & A Body Shape Index (ABSI) Calculator compute its result?

It evaluates WHtR = Waist_cm / Height_cm; ABSI = Waist_m / [ BMI^(2/3) × Height_m^(1/2) ] directly in your browser and updates three custom SVG visualizations in real time.

Can I use Goal Seek to solve backwards for a target lab value or pace?

Yes. Click "🎯 Goal Seek" in the results toolbar to solve backwards for any numeric input parameter.

Are my health and biometric inputs kept private?

Yes. All calculations run 100% locally on your device with zero external transmission.

Waist-to-Height Ratio (WHtR), Conicity Index & A Body Shape Index (ABSI) Calculator: inputs, method, and how to read the result

Assess central visceral adiposity via Waist-to-Height Ratio (<0.50), BRI, and ABSI.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Waist Circumference Cm: Horizontal waist circumference at naval/iliac crest in cm.
  • Standing Height Cm: Standing height in cm.
  • Body Weight Kg: Body weight in kg.

What the calculation includes

With the default values shown, Waist-to-Height Ratio (WHtR) is 0.48 ratio (<0.50 healthy). The calculation follows Waist-to-Height (WHtR) & ABSI Formula; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Waist Circumference Cm from 84 cm to 92 cm changes Waist-to-Height Ratio (WHtR) from 0.48 ratio (<0.50 healthy) to 0.53 ratio (<0.50 healthy). This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses peer-reviewed clinical and sports physiology formulas.
  • For educational and informational reference only; clinical scores do not replace physician judgment or laboratory reference ranges.

Scope: Global Clinical & Sports Science Consensus Check the assumptions and limitations against your situation before relying on the estimate.
