# Medical Unit Converter

Australian pathology reports give glucose and cholesterol in mmol/L, and HbA1c appears as a percentage and as mmol/mol, sometimes both. This converter starts in mmol/L with the HbA1c tab in per cent and puts the mg/dL figure beside every result. Use it to read a report, and ask your GP what it means.

## Australia rules and figures

- The AIHW gives HbA1c targets in both units, for example 7% (53 mmol/mol), and says Australian reports also use mmol/mol alone.
- Because reports use both, the Australian page starts the HbA1c tab in per cent and always shows mmol/mol as the second figure.
- Glucose and cholesterol are reported in mmol/L in Australia, so entry on the Lab values tab starts in SI units.
- Body metrics and vitals start in kilograms, centimetres and °C on the Australian page.

## How the medical unit converter works

Every test has a single factor between mmol/L style units and mg/dL style units, and the Australian page starts with SI entry. HbA1c is converted with two published equations, one for each direction.

Formula: `mg/dL = mmol/L ÷ factor, so glucose 5.0 mmol/L ÷ 0.05551 = 90.1 mg/dL; HbA1c 7.0% → (7.0 − 2.15) × 10.929 = 53 mmol/mol`

- Entry starts in SI units, so you type mmol/L and read mg/dL. The HbA1c tab starts with the percentage, and a small list switches it to mmol/mol.
- AIHW gives HbA1c targets in both units, so the page does not force one: both are shown on every HbA1c result.
- Creatinine uses 88.4 between mg/dL and µmol/L, uric acid 59.48 and urea nitrogen 0.357.
- Range badges use one adult interval kept in mg/dL, so a pathology report's own interval is the better reference.
- Weight and height start in kilograms and centimetres, and temperature in °C.

## How to use the medical unit converter

1. **Search for the test.** Type part of a name, unit or panel into the box, or pick a panel such as Lipids or Kidney.
2. **Confirm the unit you are typing.** The button shows SI (mmol/L) at the start. Press it to enter mg/dL results instead.
3. **Enter your value.** Type the figure from the report and the second unit and badge appear on the same row.
4. **Convert HbA1c.** Open the HbA1c tab to type a percentage and see mmol/mol and average glucose, or switch the unit to type mmol/mol.
5. **Try body metrics and vitals.** Height (cm), weight (kg) and temperature (°C) are the starting units on those tabs.
6. **Copy or export.** Copy and Export CSV take only the rows with a value. Reset empties the page.

## Example: Glucose, creatinine and HbA1c in Australian units

A glucose of 5.0 mmol/L shows as 90.1 mg/dL with an In range badge, and a creatinine of 80 µmol/L shows as 0.905 mg/dL. On the HbA1c tab, 7.0% converts to 53 mmol/mol, the pairing AIHW gives for a 7% target, and an average glucose estimate of 154 mg/dL (8.6 mmol/L). The badge text on that tab is a banding, not a diagnosis.

## When to use the medical unit converter

- **Reading an overseas report.** Enter mg/dL values from a US or Indian report and see mmol/L.
- **Matching percentage and mmol/mol.** See the two HbA1c units side by side when a letter gives only one.
- **Looking at kidney figures.** Convert creatinine between µmol/L and mg/dL.
- **Taking notes to the GP.** Copy the converted rows into your phone before an appointment.

## What the medical unit converter does not do

- Ranges on this page are single adult intervals, not the ones printed by your pathology provider. Trust your own report.
- Converting a value does not tell you what to do about it. Ask your GP before changing anything about your care.
- The per cent to mmol/mol step follows the IFCC equation and is an approximation, so a lab's own printed pair may differ slightly.
- Entered values are not stored, and Reset clears the page.

## When something else is a better fit

- **When you want your own interpretation of a result**, use your clinician, who reads results against the lab's printed range and your history.
- **When you want a general unit converter for length, weight or volume**, use the [Unit Converter](https://aumnitools.com/tool/unit-converter.md).
- **When you want body metrics with more measurements**, use the [BMI Calculator](https://aumnitools.com/tool/bmi-calculator.md).

## Questions about the medical unit converter

### Which HbA1c unit does my report use?

It may show a percentage, mmol/mol or both. The AIHW gives targets in both, for example 7% (53 mmol/mol), so the tab converts either way.

### How do I turn glucose in mmol/L into mg/dL?

Divide by 0.05551. A glucose of 5.0 mmol/L becomes 90.1 mg/dL.

### What is 80 µmol/L of creatinine in mg/dL?

Divide by 88.4, giving 0.905 mg/dL. The tool shows it to three decimal places because the value is below 1.

### Does an In range badge mean my result is fine?

Not necessarily. The badge compares one number with a fixed interval and ignores your age, health and the lab's own range. Your GP reads the result.

### Will this change how I take my medicines?

No. It only converts units. Treatment changes should come from your GP or specialist.
