mg/dL to mmol/L Conversion Formula

To convert cholesterol from milligrams per decilitre (the US unit) to millimoles per litre (the unit printed on Canadian lab reports), divide the mg/dL value by 38.67, or equivalently multiply by 0.02586. The divisor reflects the molar mass of cholesterol, about 386.7 grams per mole.

Milligrams per Deciliter and Millimoles per Liter Explained

Milligrams per Deciliter (mg/dL)

Milligrams per deciliter is the mass-based unit for blood cholesterol on US lab reports: it counts the milligrams of cholesterol carried in each 100 millilitres of blood. Because the cholesterol is weighed rather than counted, values run high — desirable total cholesterol stays under 200 mg/dL, risky readings climb past 240 mg/dL, and LDL targets such as 100 mg/dL appear throughout American guidelines.

Where it is used: The default on lipid panels in the United States — the format you will see on bloodwork from a US clinic, an employer screening, or a snowbird check-up.

Origin: Descended from early twentieth-century American clinical chemistry, which standardized results as measured weight per volume of serum and retained the convention after Canada and the rest of the world went SI.

Millimoles per Liter (mmol/L)

Millimoles per litre is the SI unit for blood cholesterol, stating how many millimoles are dissolved in a litre of plasma. One millimole is roughly 602 sextillion molecules, so the unit measures particle count instead of mass. The resulting numbers are compact — most lipid panels land between 2 and 8 mmol/L — which is why a Canadian report looks so much smaller than the equivalent US figure.

Where it is used: Standard on lipid panels in every Canadian province and territory, as well as the United Kingdom, Australia, New Zealand, and continental Europe.

Origin: Arrived with the SI-unit modernization of Canadian and European clinical laboratories in the 1970s and 1980s, replacing mass-based reporting nearly everywhere except the United States.

When You Need Milligrams per Deciliter to Millimoles per Liter Conversions

Preparing a US Report for Your Canadian Doctor

Before your follow-up in Toronto, Vancouver, or Halifax, translate your American panel: a total of 190 mg/dL becomes 4.913 mmol/L and an HDL of 60 mg/dL becomes 1.552 mmol/L, so your file lines up with the reference ranges your family doctor sees every day.

Checking Against Canadian Heart-Health Guidance

Heart & Stroke and Canadian cardiovascular guidance flag a total cholesterol of about 5.2 mmol/L as the desirable ceiling. Your US result of 193 mg/dL converts to 4.99 mmol/L — just inside the line — while 200 mg/dL (5.172 mmol/L) sits right at it.

Screening for a Clinical Trial in Canada

Cardiology trials run out of teaching hospitals in Toronto, Montreal, and Vancouver often set LDL entry thresholds such as 4.9 mmol/L or 3.4 mmol/L. Converting a US LDL of 190 mg/dL (4.913 mmol/L) or 130 mg/dL (3.362 mmol/L) shows immediately where you stand against the criteria.

Reconciling Snowbird Bloodwork with Home Records

If your last Canadian check-up showed a total of 5.2 mmol/L and your winter lab work in Arizona printed 201 mg/dL, converting gives about 5.198 mmol/L — close enough to confirm nothing has changed between the two systems.

How to Use

  1. 1

    Enter Your mg/dL Value

    Type the number printed on your US lab slip — say, 130 for an LDL of 130 mg/dL from a walk-in clinic during a winter in Arizona

  2. 2

    See the mmol/L Result

    It converts instantly: 130 mg/dL = 3.362 mmol/L, the same figure your family doctor in Ottawa or your pharmacist in Calgary expects to see

  3. 3

    Copy or Reverse

    Copy the mmol/L value onto your Canadian chart, or click Swap to turn an mmol/L figure from a provincial lab back into mg/dL for a US provider

  4. 4

    Check the Table

    Confirm neighbouring anchors like 100 mg/dL = 2.586 mmol/L or 190 mg/dL = 4.913 mmol/L

Frequently Asked Questions

How many mmol/L is 1 mg/dL of cholesterol?
One mg/dL equals 0.02586 mmol/L. Because such a small multiplier is awkward to work with mentally, divide the mg/dL value by 38.67 instead — it is the same factor viewed from the other direction.
How do I convert my cholesterol from mg/dL to mmol/L?
Divide the mg/dL value by 38.67. A total cholesterol of 220 mg/dL is 220 ÷ 38.67 = 5.689 mmol/L. A quick estimate: divide by 40, then add about 3.5 percent.
What is 200 mg/dL in mmol/L?
200 mg/dL equals 5.172 mmol/L. It is the classic boundary number: US labs call 200 the top of the desirable range, while Canadian labs treat about 5.2 mmol/L as the desirable ceiling — essentially the same line.
Which countries use mg/dL for cholesterol?
The United States reports cholesterol in mg/dL, and a few other countries have kept the habit. Canadian labs — from St. John's to Victoria — along with the UK, Australia, New Zealand, and most of Europe report in mmol/L instead. Dividing any US value by 38.67 makes the two systems directly comparable.
Does the 38.67 factor work for triglycerides too?
No. Triglycerides have a different molar mass and convert at roughly 88.57 mg/dL per mmol/L. Only total cholesterol, LDL, and HDL — the same molecule in different lipoprotein packages — share the 38.67 divisor. If your US requisition includes triglycerides, convert those separately.
Is 200 mg/dL cholesterol high?
200 mg/dL (5.172 mmol/L) sits right at the dividing line. Canadian labs generally consider total cholesterol desirable below about 5.2 mmol/L, and 240 mg/dL (6.206 mmol/L) is classed as high on both sides of the border. Right at the line, your family doctor will weigh LDL, HDL, blood pressure, and other risk factors before drawing conclusions.
Why do Canadian labs report cholesterol in mmol/L?
Canadian laboratories adopted SI units when the country went metric in the 1970s and 1980s, so they report cholesterol as a particle concentration rather than a weight. The same blood that reads 150 mg/dL in a US lab prints as 3.879 mmol/L in Toronto, Montreal, or Vancouver — just divide any American result by 38.67 to match it.
What is 100 mg/dL in mmol/L?
100 mg/dL equals 2.586 mmol/L. US guidelines call this the optimal LDL level, and Canadian cardiovascular guidance often phrases a similar goal as keeping LDL under about 2.6 mmol/L for people at lower risk.

About Our mg/dL to mmol/L Cholesterol Converter for Canadians

This free converter translates American lipid results into the mmol/L units used on lab reports across Canada. Whether you are a snowbird back from Arizona with bloodwork from a US clinic, a cross-border commuter whose workplace health screening was done stateside, or simply comparing your numbers against Heart & Stroke guidance, the tool gives instant, precise answers your family doctor will recognize. Every cholesterol fraction — total, LDL, and HDL — divides by the same factor of 38.67, so one converter handles the whole panel.

Expert Tips for mg/dL to mmol/L Conversion

1

mg/dL ÷ 38.67 = mmol/L exactly. Multiplying by 0.02586 gives the same result, because 0.02586 is simply 1 ÷ 38.67 rounded.

2

Four anchors cover most conversations: 200 mg/dL = 5.172 mmol/L (desirable ceiling), 240 = 6.206 (high), 100 = 2.586 (optimal LDL), and 40 = 1.034 (protective HDL floor).

3

A fast mental route is divide by 40, then add 3.5 percent: 220 mg/dL becomes 5.5, then about 5.69 mmol/L — within 0.01 of the exact 5.689.

4

Keep the factor strictly for cholesterol. Triglycerides on the same requisition convert with roughly 88.57 instead of 38.67, so a US-to-metric triglyceride conversion needs its own divisor.

5

When comparing HDL with the reference ranges printed on Canadian reports, remember the protective floor is commonly quoted as 40 mg/dL (1.034 mmol/L) for men and 50 mg/dL (1.293 mmol/L) for women.
