How is human energy measured?
In human biol- ogy research, energy is most often measured in kilocalo- ries (kcal). Another common unit for measuring energy is the joule or the kilojoule [1 kilojoule (kJ) 5 1,000 J], with the conver- sion between calories and joules being 1 kcal 5 4.184 kJ.
How is energy in food measured?
Energy is measured in units of kilocalories (kcal) or kilojoules (kJ). One kilocalorie (1 kcal) is equal to 4.18 kilojoules (4.18 kJ). The amount of energy a food contains per gram is known as its energy density so we can describe fat as more energy dense than protein or carbohydrate.

How do you write units?
Units: The names of all units start with a lower case letter except, of course, at the beginning of the sentence. There is one exception: in “degree Celsius” (symbol °C) the unit “degree” is lower case but the modifier “Celsius” is capitalized. Thus, body temperature is written as 37 degrees Celsius.
Do you put space between number and unit?
There is a space between the numerical value and unit symbol, even when the value is used in an adjectival sense, except in the case of superscript units for plane angle. If the spelled-out name of a unit is used, the normal rules of English apply: “a roll of 35-millimeter film.”

What makes up 1 gram?
Gram (measure): A unit of measurement of weight and mass in the metric system. In weight, a gram is equal to a thousandth of a kilogram. In mass, a gram is equal to a thousandth of a liter (one cubic centimeter) of water at 4 degrees centigrade. Its symbol is g.
