For water and other equally fluid products (such as milk), you can convert at the rate 1g=1ml. (So 1000g in 1 litre, which is 1000ml).
However for less fluid products (such as yogurt, honey, oil, cream etc...) this conversion becomes more inaccurate the less fluid the substance is, so it should no be used as a conversion. To convert less fluid substances from a liquid measure to a weight measure, there is no standardised conversion - you should be able to work it out by measuring how much a tablespoon of the substance weighs, and multiplying it by 68. (Since approx 6.8 tbl in 100ml, so you need ten times this amount).
The question is strange, like: "How many liters are 120 volts"?
fats=9 calories per gram
Protein has 4 calories per gram.
Protein and Carbohydrates are both 4 calories per gram, and Fat is 9 calories per gram.
There is one gram per ML of water, and 1000 ML in a liter. There are 2,000 grams or two kilograms in two liters of water.
4 calories per gram of carbohydrate
Protein contains 4 calories per gram.
Fat has 9 kilocalories per gram. Carbohydrates and protein both have 4 kilocalories per gram, and alcohol has 7 kilocalories per gram.
To convert 1 gram per gram-mole to pounds per pound-mole, you would multiply by 0.00220462.
It depends upon the substance and the temperature. For water at room temperature the volume would be 0.0125L
9 calories of energy per gram. 9 calories of energy per gram.
4 per gram the other macronutrients are: protein - 4 per gram (same as carbs) fat - 9 per gram
