How to use the mmol/L to mg/dL calculator
Using the mmol/L to mg/dL calculator is very easy. All you have to do is pick one of the molecules from the Molecule
dropdown field, input either the mmol/L or mg/dL value, and see the result!
If you want to convert the units of a different molecule not listed in the dropdown field, click on the heading Custom molar mass
. There, you can enter the customized molar mass along with either the mmol/L or mg/dL value. The mmol/L to mg/dL calculator will instantly give you the converted result.

Converting blood sugar from mmol/L to mg/dL
To convert blood sugar from mmol/L to mg/dL, you have to:

Find the molar mass of glucose:
180.156 g/mol
. 
Convert the molar mass from g/mol to mg/mmol. Since both values scale down proportionally:
180.156 g/mol = 180.156 mg/mmol

Multiply the molar mass from the step above by the mmol/L value you've got.

Convert the result you got in Step 3 from mg/L to mg/dL by dividing by 10.

That's it! Now you know how to convert glucose mmol/L to mg/dL!
Alternatively, you can input your data and let our calculator do the work for you! Then, you can go to Omni Calculator's blood sugar converter to check whether your glucose levels are alright.
Converting cholesterol from mmol/L to mg/dL
Converting cholesterol from mmol/L to mg/dL couldn't be easier. In fact, it is just about the same as what we did for blood sugar, only that now we use the molar mass of cholesterol (TC, LDL, HDL) instead. To calculate it, use the following equation:
cholesterol (mg/dL) = cholesterol (mmol/L) × 386.654/10
where 386.654
is the molar mass of the cholesterol in mg/mmol.

How to convert from mg/dL to mmol/L
To convert from mg/dL to mmol/L, all you have to do is:

Convert from mg/dL to mg/L. To do this, multiply the mg/dL value by 10 (1L = 10 dL). For example:
0.2 mg/dL × 10 = 2 mg/L

Find the molar mass of the substance at hand. For the sake of this example, let's say we are talking about bilirubin, which has a molar mass of
584.66 g/mol
. 
Convert the molar mass from g/mol to mg/mmol. As both values decrease by an equal factor:
584.66 g/mol = 584.66 mg/mmol

Divide the value in mg/L by the molar mass in mg/mmol. In our case:
2 mg/L / 584.66 mg/mmol = 0.00034 mmol/L

That's it! You have now converted from mg/dL to mmol/L.
How do you convert from mmol/L to mg/dL?
To convert from mmol/L to mg/dL:

Find out the molar mass of the molecule at hand.

Multiply the molar mass found by the mmol/L value.

Divide the result obtained in the previous step by 10.

That's it! You have now converted from mmol/L to mg/dL.
What is 6.6 mmol/L in mg/dL?
Assuming we are talking about triglycerides, 6.6 mmol/L is equivalent to 584.56 mg/dL. To find out what 6.6 mmol/L to mg/dL is:

Find the molar mass of the triglycerides:
885.7 mg/mmol
. 
Multiply it by 6.6 mmol/L:
6.6 mmol/L × 885.7 mg/mmol = 5,845.62 mg/L

Convert the units of your result by multiplying by 0.1:
5,845.62 mg/L × 0.1 ≈ 584.56 mg/dL

That's it!
How do I convert 7.8 mmol/L to mg/dL?
To convert 7.8 mmol/L to mg/dL, you have to:

Divide the molar mass of the substance at hand by 10. Assuming we are talking about blood urea nitrogen (BUN) (28 g/mol):
28 / 10 = 2.8

Multiply it by 7.8:
7.8 × 2.8 = 21.84

Add the
mg/dL
unit to the end of your result:21.84 mg/dL
. 
That's it!
How do you convert ketones from mg/dL to mmol/L?
To convert ketones from mg/dL to mmol/L:

Find out which ketone you are converting: 3HB (3βhydroxybutyrate), acetoacetate (AcAc), or acetone (C3H6O).

Find the molar mass of the ketone at hand. It should be either 104.105 g/mol (3HB), 101.08 g/mol (AcAc), or 58.08 g/mol (C3H6O).

Divide the molar mass found by 10.

Divide the mg/dL value by the above result.

That's it!
How do I convert 300 mg/dL to mmol/L?
To convert 300 mg/dL to mmol/L:

Find the molar mass of the molecule at hand.

Divide the molar mass found by 10.

Divide 300 by the result obtained above to convert from mg/dL to mmol/L.

Put the
mmol/L
unit at the end of your result. 
Congratulations! You have now converted 300 mg/dL to mmol/L.
