i need to know the density of a varnish.. is it applicable to use kg as a unit of measurement in measuring varnish?
thanks.
Either weight or volume would be suitable.
Different varnishes may have different densities depending on whether they are an oiul or water formulation and amount of pigments. Oil based would probably be a little under 1 kg/L (oil-based paint could be over because paint has much more pigment). Water-based would likely be slightly over 1 kg/L. You would have to measure it or get manufacturer's data to have any accuracy.
i am not expert in math, how to convert 1kg to liter
You have to know the density of the substance.
Water is about 1 kg/L, so 1 L. Things lighter than water, oil, gasoline, would be more than 1 L. Heavily pigmented paints and other things heavier than water would be less than 1 L. If you can find (or measure) the density of the substance, divide the mass by it.
i have wheat which is having a moisture content of 10.5% and i have conditioned it (add water and allow water to get absorbed into the grain) and the moisture has gone up to 16.4%.the water percentage added to the grain is 5.9%.How can i convert this percentage into litres and then kilograms

Lets start with 1 metric ton of the 10.5% moisture wheat.
It is 105 kg water, and 895 kg of bone-dry wheat.
After moisture is added, it is still 895 kg of bone-dry wheat, but that is only 83.6% (100 - 16.4) of total mass. Total mass must be 895 kg/0.836 = 1070.6 kg, so 70.6 kg of water must have been added per metric ton.
can someone help me by giving me the formula to convert Kg to Litres when it is Hydrogen for the Kg and petrol for the Litres.
The comparison is usually done on the basis of heating value. For an engine, the Lower Heating Value is the usual comparison. Figures vary, particularly lot to lot for gasoline. Using DoE typical figures:
1 kg H2 = 120.21 MJ/kg
and gasoline (petrol) 42.358 MJ/kg and 0.7476 kg/L (= 31.667 MJ/L)
Thus 1 kg H2 = 3.796 L gasoline, based on LHV equivalence.
