Calculator
BMI Calculator
Calculate body mass index from weight and height.
Calculator Inputs
Height must be a valid number.
Legend
BMI legend
BMI is weight in kilograms divided by height in meters squared. It is a screening calculation, not a diagnosis.
Input meaning
- Weight: enter the measured, quoted, or hospital-approved value in kg.
- Height: enter the measured, quoted, or hospital-approved value in cm.
Result interpretation
- The category is a general adult screening category.
- Clinical interpretation can vary with age, pregnancy, muscle mass, edema, and local clinical policy.
Assumptions
- BMI is a screening metric, not a diagnosis.
- Clinical interpretation should be done by qualified healthcare professionals.
Biomedical use
- Useful as a simple educational calculator; not intended to replace clinical assessment.
How to identify the required values
Use these examples and common working ranges to choose values from gauges, labels, manuals, datasheets, RFQs, service reports, CMMS records, or hospital planning assumptions.
| Field | Example value | Common range | Tip |
|---|---|---|---|
| Weight | 70 kg. | Use actual patient weight for clinical dosing examples; procurement demos often model 70 kg adult cases. | Use actual patient weight for clinical examples. |
| Height | 170 cm. | Usually 1 cm or higher; use the real hospital value. | Enter centimeters, not meters; 1.70 m should be entered as 170. |
Common ranges are starting points for hospital planning. For final procurement, acceptance testing, electrical design, medical gas design, radiation shielding, dialysis water systems, or clinical use, replace the example values with site-specific data and vendor-confirmed figures.
Input Checklist
Confirm these values before relying on the output for procurement, PM, or service planning.
- Weight
- Height
Safety And Engineering Notes
Use calculator outputs as planning estimates and verify critical systems with calibrated measurement or qualified engineering review.
- BMI is a screening metric, not a diagnosis.
- Clinical interpretation should be done by qualified healthcare professionals.
