Clinical Height Converter

Convert height between centimetres, metres, inches and feet-and-inches with the exact 2.54 cm inch and clinical rounding steps.

The Clinical Height Converter changes a height between centimetres, metres, total inches and feet-and-inches using the exact international inch of 2.54 cm, so a foot is exactly 30.48 cm. It applies the recording step your chart uses — 0.1 cm on a stadiometer, or half and whole centimetres on many forms — reports how far that rounding moved the value, and gives the height squared in square metres that a BMI calculation needs. It is for filling in medical forms, growth charts and dosing calculations where the units differ from the ones on the measuring device.

Why use Clinical Height Converter

• Exact inch

  Uses 2.54 cm rather than 2.5, which drifts by nearly 3 cm across an adult height.

• Carry handled

  Feet-and-inches output rolls 11.98 in up to the next whole foot instead of printing 12 in.

• BMI ready

  Shows metres and metres squared alongside, so the BMI denominator does not need a second calculation.

Common use cases

• Convert a 5 ft 11 in height on a US form into the 180.34 cm a metric record expects.
• Get the height squared in square metres before calculating BMI by hand.
• Record a stadiometer reading to the nearest 0.1 cm for a paediatric growth chart.
• Check how much rounding to the nearest whole centimetre shifts a height used in a body surface area formula.
