mmol/L to mg/dL Conversion Formula

To convert cholesterol from millimoles per liter to milligrams per deciliter, 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 liter and a deciliter.

Millimoles per Liter and Milligrams per Deciliter Explained

Millimoles per Liter (mmol/L)

Millimoles per liter 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 liter 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 Canada, the United Kingdom, Australia, New Zealand, and most of continental Europe.

Origin: Adopted as clinical chemistry laboratories metricized during the 1970s and 1980s, when lab medicine moved to SI units for consistency across the medical sciences.

Milligrams per Deciliter (mg/dL)

Milligrams per deciliter expresses cholesterol as mass: the number of milligrams of cholesterol carried in one tenth of a liter (100 milliliters) 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 standardized results as measured weight per 100 milliliters of serum and never switched to SI units.

When You Need Millimoles per Liter to Milligrams per Deciliter Conversions

Reading a Canadian Lipid Report in US Terms

Your Canadian total cholesterol of 5.2 mmol/L equals 201.08 mg/dL — right at the line where US lab slips print an under-200 flag, so knowing both units explains why the two reports flag the same blood differently.

Using American Cardiovascular Risk Calculators

US risk tools ask for total and HDL cholesterol in mg/dL. Entering your European report 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 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 review.

Tracking Statin Follow-Up Across Borders

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 percent improvement expressed both ways for whichever clinician reads it.

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 liter and a deciliter.
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 percent.
What is 5.2 mmol/L in mg/dL?
5.2 mmol/L equals 201.08 mg/dL. This is a pivotal number: Canadian and European labs treat 5.2 mmol/L as the top of the desirable range, while US labs flag 200 mg/dL — essentially the same threshold written in different units.
Why does Canada use mmol/L but the US use mg/dL for cholesterol?
Canadian laboratory medicine adopted SI units in the 1980s, 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.
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. 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 exactly at the upper edge of the desirable range. Total cholesterol is generally considered desirable below 5.2 mmol/L and high above 6.2 mmol/L (239.75 mg/dL), so at exactly 5.2 your clinician will focus on LDL, HDL, and overall cardiovascular risk rather than the total alone.
Why is LDL in mmol in Canada?
Canadian labs standardized 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 a Canadian LDL below 2.6 mmol/L matches the American cut-off.
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).

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 deciliter of blood weighs 38.67 mg, so mg/dL = mmol/L × 38.67.

2

Memorize four anchors and you can sanity-check any report: 5.2 mmol/L ≈ 201 mg/dL (top of desirable), 6.2 mmol/L ≈ 240 mg/dL (high), 2.6 mmol/L ≈ 100 mg/dL (optimal LDL), and 1.0 mmol/L ≈ 39 mg/dL (protective 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 math.

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 percent reduction that statin follow-up visits measure precisely.
