Generally, you measure dry weight on a scale.

This cannot be sensibly answered. Milliliters (mL) is a measure of volume, dry ounces are a measure of weight or mass.
a gram is a measure of dry weight. a milliliter is a measure of liquid weight. you can't convert them.
A kilogram is a measure of mass, not of weight. They are not the same thing!
This cannot be determined because tablespoons is a measure of volume and grams is a measure of weight.
dry measure
You don't A count per second is a measure of how many decays occur within a second. A sievert is a measure of the dose equivalent. This requires knowledge of the isotope, the organism or part of the organism which is receiving the dose, the weight of the organism and the weighting factors which accompany them.
If I ignore your horrible grammar, I think you're asking what biomass is/means... correct? Biomass is the dry mass of a once living organism. So biomass is the mass of an organism minus the weight of the water in/on the organism.
A peck is a measure of dry volume - not of weight. 8 dry quarts (16 dry pints) - note not for liquids. Thus the weight would depend on what was being measured: feathers or lead sinkers.
A cup is a measure of volume, and dry ounces is a weight, The only way one can determine the weight of a substance that will fit into a specific volume is to measure the specific substance.
You can't, millilitres is a measure of VOLUME Ounces is a measure of WEIGHT The two can not be equated without knowing the density of the matter being measured.
