4. The Metric System
Like most money systems  are based on multiples of 10. Each unit is either 10 times greater than the nextsmaller amount  or it is 1/10th the size of the nextlarger amount. And since the metric system is based on 10s  it works quite naturally wit

Multiply the number of grams by 0.035.
The basic unit of metric capacity is the liter (pronounced as LEEter). Smaller units are the milliliter (1/1000 of a liter) and the microliter (1millionth of a liter). A kiloliter is a thousand liters  but we seldom find that unit used anywhere. A

17. Metric Measures of Mass and Weight
Add the numerators to get the numerator for the sum. Assign the common denominator to the sum. Reduce or simplify the result as necessary.
Fractions can be added only when they have the same denominator. When they do not  you must adjust them so that the denominators are the same.
(also known as 'unit analysis' or 'dimensional analysis') is based on the principal that multiplying something by '1' doesn't change the value  and that any value divided by the same value equals '1'.
The basic metric unit for mass (or weight) is the gram (g). The most common unit that is smaller than a gram is the milligram (1/1000th of a gram). The most common larger unit of mass is the kilogram (1000 grams).
