Re: mmol/l to mg/l

Mrs X u seem 2 b quite knwlegdgeabl. So pls cld u tell me d conversion factor of mg/dl to mmol/l for lipids in general,cholesterol,phospholipids,triacylglyceral and free fatty acid. Thanks.

Hi,

They all have different g/mmol weights, so therefore have different mg/dL to mmol/L conversions.

All we can tell you to um, "help" is that unfortunately, you will have to find out the molecular weight for your substance, or if you post it, we might be able to help find out where it is posted on the net.

There are 10dL in 1L though. 1dL is 100mL, 1L is 1000mL.

Re: mmol/l to mg/l

If you google vicnet converters substance
This tool will convert units (amount of substance, concentration) of clinical data between conventional units and SI units.

Please see post #11. The conversion is different for every substance. You have to know what it is, and its molar mass.

Its done thanks,... correct

Re: mmol/l to mg/l

Hi there

This is an old thread, but the key to this conversion is that you are trying to convert a quantity of something (number of atoms per litre or mmol/l) to a mass (mg/l) or vice versa. It should be evident then that there is no one conversion factor - until you know the molecular mass of the the substance you are converting (e.g. CaCO3).

So, for water hardness, you may be wanting to convert mg/l of CaCO3 to mmol/l. For this you need to know that the molecular mass of CaCO3 is approx. 100. All you have to do now is divide the mg/l by the molecular mass. E.g., in my area the water hardness is 46 mg/l of CaCO3 (the water is considered soft). To get the mmol/l, you just divide by 100, so it is .46 mmol/l.

Hope this helps.

A 1mol/L (1M or 1molar) solution has 6.0221415 x 10²³ molecules per litre, and is in g/L A 1mmol/L (1millimolar) solution is 1000 times more dilute, and there are 1000mg in 1g. So to go from mmol/L to mg/L, multiply by the molecular weight. To go from mg/L to mmol/L divide by the molecular weight. Lead is poisonous, particularly in solution. If you are really dealing with these solutions, is it possible to get the help of someone who is trained in the use of chemical poisons?
**Your information helped me alot with conversions! very simple and straight forward! THANK YOU!!**
