Gram is a weight measure, and Litres are a volume measure. If you have 1 liter of water, then it weighs 1000 grams (assuming that it is at standard temperature and pressure [STP]). If it is 1 liter of something else, then the number of grams differs.

None.

A milligram is a measure of mass. A litre is a measure of volume. The two measure different things and,according to basic principles of dimensional analysis, conversion from one to the other is not valid.

If you are not convinced, consider a litre of air. How many milligrams? Next consider a litre of lead. How many milligrams?

The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.

Some people still believe that there is a conversion in relation to pure water but that is only approximately true. Until 1964 (nearly 50 year ago!) a litre was defined as the volume of one kilogram of pure water at 4 degrees Celsius and at a pressure of 760 millimetres of Mercury. With that definition a conversion would have been valid - but only for pure water and only under those conditions. In any case that definition of a litre was abandoned in favour of 1 litre =1000 cubic centimetres.

In fact the density of pure water, at 4 deg C and 760 ml of mercury is 999.9720 kg/metre3

There is no answer because milligrams is a measurement of weight and 1 L is volume. If you meant how heavy 1L is in milligrams, this depends on the substance's density.

There is no equivalent because mg is weight and litre is volume.


How do you convert mg l to percent?

mg/l is milligrams per litre….or milligrams in one litre of water… this is a weight by volume relationship with mg the weight and litre the volume…. For considering percentages, we need both units to be of same dimension i.e. weight by weight or volume by volume that means you have to convert mg/l to either mg/g or ml/l we consider converting to mg/g (or any other WEIGHT unit) Converting mg/l to mg/g or mg/Kg As you know density of water is 1 gm/ml…..which means when you take 1ml of water it will be 1 gram So if you take 1000 ml it will be 1000 grams Or 1 litre of water will weigh 1 kg Which means you can write mg/l as mg/kg (as 1 litre of water is 1kg) So suppose you got chloride content in soil as 34 mg/l then you can also say it is 34 mg/kg Now mg/kg is also known as 1ppm i.e. 1mg/kg = 1mg/1000grams= 1mg/1000000 mg (we have converted everything into milligrams) So all that remains is 1/1000000 or 1/ 1 million or 1 part per million or 1ppm Percentage is parts per hundred So if a chemical has concentration of 34 parts in a million, how much will it be in just hundred So in 1 lakh it will be 3.4, In 10000 there will be 0.34, In 1000 there will be 0.034 and in 100 there will be 0.0034 Or 34 mg/ kg will be 34 mg / 1000000 mg So 34 mg is concentration in 1000000 mg So % will be 34 x 100 ___________ = 0.0034% 1000000

If 5 mg per liter how many grams in 10000 liters?

To convert from mg to g, divide by 1000. Therefore, 5 mg per liter is equivalent to 0.005 g per liter. In 10000 liters, there would be 0.005 g * 10000 = 50 grams.
