The FDA and others are moving away from "serving" in describing fruits and vegetables, probably since a person's definition of a serving of food differs very much from the academic definition. Instead, the FDA now gives volume (cups) as it's indictator for fruit and vegetable targets. Some examples appear here: http://www.fruitsandveggiesmatter.gov/what/examples.html
One serving would be 400 grams (2000 grams / 5 people).
For pure water one can say: 1 milliliter of water weighs 1 gram. 1 milliliter of vegetable oil weighs a bit less.
One milliliter of vegetable oil used for cooking has 8.1 calories. There would be 120 calories in one tablespoon of vegetable oil.
Depends what you serve. -Salad - 0 fat, -pork chop, lots of fat.
8 dollars for one bottle and one tbls (15 mL) is 8 cents
One ratti is equivalent to 0.1215 grams.
There are about 453.6 grams in one pound.
There are 10 grams in one decagram.
100 grams
One cup of veggies equals 5 grams.
happily liquids weigh what their volume is so 30 ml weighs 30 grams. veg oil is pretty dense so it can be more but you are probably just using the oil to saute in so its not a big deal.
One teenth of a kilogram is equivalent to 6.25 grams.
