    Medical Unit Converter

    🇮🇳 India version

    Indian laboratories and ICMR guidance use mg/dL for glucose and cholesterol and per cent for HbA1c, so this converter opens in those units. It shows the mmol/L and mmol/mol equivalents beside each result, which helps with reports from the UK, Australia or Canada. Your doctor can explain what a result means for you.

    Medical Unit Converter

    Convert 32 lab values between conventional (mg/dL) and SI (mmol/L) units, with typical adult reference intervals for context

    Reference ranges are not universal

    The intervals here are typical adult values. Real ranges vary by laboratory, assay, age, sex, pregnancy and ethnicity — the range printed on your own report is the one that applies to your result. A value outside a range is not by itself a diagnosis, and a value inside one does not rule anything out.

    Enter your results

    Labs here report glucose and cholesterol in mg/dL and HbA1c in %, so that unit comes first. ICMR uses mg/dL and %: fasting glucose 126 mg/dL or more and HbA1c 6.5% or more is diabetes; LDL target below 100 mg/dL. Sources: ICMR: Standard Treatment Workflow, type 2 diabetes.

    Why two sets of units exist

    Mass versus moles

    Conventional units express concentration as mass per volume (mg/dL). SI units express it as moles per volume (mmol/L), which is chemically more meaningful because reactions happen between numbers of molecules, not grams.

    The conversion factor is therefore specific to each substance — it is 10 divided by the molecular weight. This is why glucose and cholesterol, both reported in mg/dL, use completely different factors.

    Where conversion does not apply

    Some pairs are identical rather than converted: mEq/L equals mmol/L for monovalent ions like sodium and potassium, and ng/mL equals µg/L by definition. Others, like HbA1c, are related by fitted equations rather than chemistry.

    Enzyme activities (ALT, AST, alkaline phosphatase) are reported in units per litre and are not converted at all, which is why they are not listed here.

    Not a diagnosis
    A unit converter with reference context, not a clinical decision tool. Interpreting lab results requires the full picture — your history, your symptoms, and the range your own laboratory reports. Discuss results with the clinician who ordered them.

    India rules and figures

    • ICMR uses mg/dL and per cent in its type 2 diabetes workflow, so the page starts glucose and cholesterol entry in mg/dL and HbA1c in %.
    • ICMR describes a fasting glucose of 126 mg/dL or more and an HbA1c of 6.5% or more as diabetes. A doctor makes the diagnosis, not this page.
    • ICMR gives an LDL target below 100 mg/dL, which matches the upper limit the converter stores for LDL cholesterol.
    • Indian height starts in feet and inches on the body tab, with weight in kilograms and temperature in °C.

    How the medical unit converter works

    Every test has a factor that turns mg/dL style units into mmol/L style units, and the Indian page starts with you typing mg/dL. HbA1c uses two equations for mmol/mol and average glucose.

    mmol/L = mg/dL × factor, so glucose 126 mg/dL × 0.05551 = 6.99 mmol/L; HbA1c 6.5% → (6.5 − 2.15) × 10.929 = 48 mmol/mol

    • Entry starts in conventional units (mg/dL), and one press of the entry button switches to mmol/L.
    • The HbA1c tab starts in per cent and shows mmol/mol and average glucose; a small list lets you type mmol/mol instead.
    • Cholesterol rows use 0.02586, triglycerides 0.01129 and creatinine 88.4 between the unit systems.
    • Badges compare each value with a single adult interval in mg/dL, so a lab's own printed range should be used first.
    • Height starts in feet and inches, weight in kilograms and temperature in °C.

    How to use the medical unit converter

    1. Search for the test. Type a name, unit or panel into the box, or choose one panel from the menu.
    2. Confirm the entry unit. The button starts at Conventional (mg/dL), the unit on most Indian reports. Press it to type mmol/L instead.
    3. Type the value. The other unit and the range badge appear on the row as you type.
    4. Convert HbA1c. The HbA1c tab starts in per cent and adds mmol/mol and average glucose in mg/dL and mmol/L.
    5. Check body and vitals. Height starts in feet and inches and weight in kilograms, and Vitals uses degrees Celsius.
    6. Copy or export. Copy and Export CSV take the rows you filled in. Reset clears them.

    Example: Glucose, LDL and HbA1c in Indian units

    A fasting glucose of 126 mg/dL converts to 6.99 mmol/L, and the badge reads Above range because it is over the stored 99 mg/dL. An LDL of 100 mg/dL is 2.59 mmol/L and reads In range, as the stored limit is 100. On the HbA1c tab, 6.5% converts to 48 mmol/mol, and an average glucose estimate near 140 mg/dL (7.8 mmol/L). These are tool bandings, not diagnoses.

    When to use the medical unit converter

    • Reading a report from abroad. Switch to mmol/L entry for a UK or Canadian report and see mg/dL.
    • Seeing HbA1c in mmol/mol. Convert a percentage to the unit used in the UK and New Zealand.
    • Reviewing a lipid panel. Convert LDL, HDL, total cholesterol and triglycerides.
    • Preparing for a visit. Copy the converted figures to show your doctor.

    What the medical unit converter does not do

    • The ranges are one adult interval for every country and do not replace the range printed by your laboratory.
    • The converter does not diagnose and should not be used to change medicines. Ask your doctor.
    • Per cent and mmol/mol are related by the IFCC fit, so the pairing is close but not exact.
    • Values you type are not stored on 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.
    • When you want body metrics with more measurements, use the BMI Calculator.

    Questions about the medical unit converter

    Which units does ICMR use?

    ICMR guidance uses mg/dL for glucose and cholesterol and per cent for HbA1c, so the page starts there.

    How do I convert 126 mg/dL of glucose to mmol/L?

    Multiply by 0.05551, the glucose factor used by this tool. The result for 126 mg/dL is 6.99 mmol/L.

    What is an HbA1c of 6.5% in mmol/mol?

    It is 48 mmol/mol using the IFCC equation. ICMR describes an HbA1c of 6.5% or more as diabetes, and the diagnosis is made by your doctor, not by this page.

    Why does an LDL of 100 mg/dL read In range?

    The stored upper limit for LDL is 100 mg/dL, matching the ICMR target of below 100, and the badge only marks values above the limit. Your doctor sets your own target.

    Can I use this to change my medicines?

    No. It converts units so you can read a report. Medicine changes are for your doctor.
