mmol/L to mg/dL Conversion Formula

To convert cholesterol from millimoles per litre to milligrams per decilitre, multiply the mmol/L value by 38.67. The factor comes from the molar mass of cholesterol (about 386.7 grams per mol) and the tenfold difference between a litre and a decilitre.

Millimoles per Liter and Milligrams per Deciliter Explained

Millimoles per Liter (mmol/L)

Millimoles per litre is the SI unit for reporting cholesterol concentration in blood plasma. Instead of weighing the cholesterol, it counts molecules: one millimole is about 602 sextillion cholesterol particles, and mmol/L states how many of those units are dissolved in each litre of blood. Typical lipid panel values fall between 2 and 8 mmol/L, so the scale is compact and a single decimal place carries real clinical meaning.

Where it is used: Used for lipid panels in Australia, New Zealand, the United Kingdom, Canada, and most of continental Europe.

Origin: Adopted as clinical chemistry laboratories metricated during the 1970s and 1980s, when pathology services in Australia and elsewhere moved to SI units for consistency across the medical sciences.

Milligrams per Deciliter (mg/dL)

Milligrams per decilitre expresses cholesterol as mass: the number of milligrams of cholesterol carried in one tenth of a litre (100 millilitres) of blood. Because cholesterol is weighed rather than counted, the numbers run large — a desirable total cholesterol sits under 200 mg/dL, an optimal LDL under 100 mg/dL, and a very high reading can exceed 300 mg/dL.

Where it is used: The standard unit on lipid panels in the United States and in much of the cardiology research it publishes.

Origin: A survivor of early twentieth-century American clinical chemistry, which standardised results as measured weight per 100 millilitres of serum and never switched to SI units.

When You Need Millimoles per Liter to Milligrams per Deciliter Conversions

Reading Your Australian Pathology Report in US Terms

Your total cholesterol of 5.2 mmol/L equals 201.08 mg/dL — just over the line where US lab portals print an over-200 flag, so knowing both units explains why an American tool might flag a result your GP called perfectly acceptable.

Using American Cardiovascular Risk Calculators

US risk tools ask for total and HDL cholesterol in mg/dL. Entering your pathology values of 6.2 mmol/L total (239.75 mg/dL) and 1.3 mmol/L HDL (50.27 mg/dL) keeps the ten-year risk estimate honest.

Comparing LDL With US Heart-Health Content

American articles quote an optimal LDL below 100 mg/dL. Your pathology report shows 3.0 mmol/L, which converts to 116.01 mg/dL — just above that target, and a useful talking point at your next GP review.

Tracking Statin Follow-Up With Your GP

If your LDL fell from 3.4 to 2.6 mmol/L after starting treatment, that is a move from 131.48 to 100.54 mg/dL — the same 23.5 per cent improvement expressed both ways, handy whether your next check-up is with a local GP or a cardiologist in the US.

Frequently Asked Questions

How many mg/dL is 1 mmol/L of cholesterol?
One mmol/L equals 38.67 mg/dL, and the same factor applies to every cholesterol fraction — total, LDL, and HDL alike. It reflects the molar mass of cholesterol (about 386.7 grams per mol) divided by the tenfold difference between a litre and a decilitre.
How do I convert my cholesterol from mmol/L to mg/dL?
Multiply the mmol/L value by 38.67. For example, a total cholesterol of 6.2 mmol/L is 6.2 × 38.67 = 239.75 mg/dL. For a quick estimate, multiply by 40 and subtract about 3.5 per cent.
What is 5.2 mmol/L in mg/dL?
5.2 mmol/L equals 201.08 mg/dL. It's also a telling number when comparing systems: Australian guidelines often aim for a total cholesterol below 5.5 mmol/L (about 213 mg/dL), while US labs flag anything over 200 mg/dL — comparable thresholds written in different units, which is exactly why a straight conversion helps.
Why do Australian pathology labs use mmol/L while the US uses mg/dL?
Australian laboratory medicine adopted SI units decades ago, so cholesterol is reported as a particle concentration in mmol/L. The US kept the older mass-per-volume convention of mg/dL. One blood sample therefore produces two very different-looking numbers — 5.2 and 201 describe the same cholesterol level, whether the sample was collected in Adelaide or Atlanta.
Is the 38.67 factor the same for HDL and LDL cholesterol?
Yes. Total cholesterol, LDL, and HDL are all the same molecule, so a single factor of 38.67 converts any of them — whether the report came from a Sydney pathology lab or a US clinic. Triglycerides are the exception: they have a different molar mass and use a factor of about 88.57, so never apply 38.67 to triglyceride values.
Is 5.2 mmol/L cholesterol high?
5.2 mmol/L (201.08 mg/dL) sits below the Australian Heart Foundation target of 5.5 mmol/L but right at the US desirable ceiling of 200 mg/dL. Readings above 6.2 mmol/L (239.75 mg/dL) are clearly high on either scale, so at 5.2 your GP will focus on LDL, HDL, and your overall cardiovascular risk rather than the total alone.
Why is LDL in mmol/L in Australia?
Australian labs standardised on SI units decades ago, so every cholesterol fraction, LDL included, is reported in mmol/L. To compare with the US optimal LDL target of under 100 mg/dL, divide by 38.67: 100 mg/dL is about 2.59 mmol/L, so an LDL below 2.6 mmol/L matches the American cut-off. Note that for many Australians on statins the local target is stricter — under 2.0 mmol/L (77.34 mg/dL) for high-risk patients.
What is 3.0 mmol/L LDL in mg/dL?
An LDL of 3.0 mmol/L equals 116.01 mg/dL. On the US scale that falls in the near-optimal band — above the optimal mark of 100 mg/dL (2.586 mmol/L) but below the borderline-high level of 160 mg/dL (4.138 mmol/L). If you have existing heart disease, your GP may aim for under 2.0 mmol/L (77.34 mg/dL), which is stricter than typical US targets.

Total cholesterol, LDL, and HDL all share the same factor of 38.67 mg/dL per mmol/L, so one converter covers your entire lipid panel.

Expert Tips for mmol/L to mg/dL Conversion

1

The exact factor 38.67 comes from the molar mass of cholesterol, roughly 386.7 grams per mol: one millimole dissolved in a decilitre of blood weighs 38.67 mg, so mg/dL = mmol/L × 38.67.

2

Memorise four anchors and you can sanity-check any report: 5.5 mmol/L ≈ 213 mg/dL (the Australian total target), 6.2 mmol/L ≈ 240 mg/dL (high on any scale), 2.0 mmol/L ≈ 77 mg/dL (the Australian LDL target for high-risk patients), and 1.0 mmol/L ≈ 39 mg/dL (a healthy HDL floor).

3

Scale around the boundary anchor: 5.172 mmol/L is exactly 200 mg/dL, so 2.586 mmol/L is 100 mg/dL and 10.34 mmol/L is 400 mg/dL without any further maths.

4

Never convert triglycerides with 38.57 or 38.67-style cholesterol factors — triglycerides use about 88.57 mg/dL per mmol/L. Only total cholesterol, LDL, and HDL share the 38.67 factor.

5

When tracking treatment over time, keep two decimals: an LDL fall from 3.4 to 2.6 mmol/L is 131.48 down to 100.54 mg/dL — a 23.5 per cent reduction your GP can measure precisely at each review.
