Weight and Mass

Like length, mass has different units of measurement. In the metric system, the units of measurement generally used in mass are milligrams, grams, kilograms. In the imperial system, ounces, the units of measurement generally used are pounds, ounces and tonnes.

Below are a few charts that show the relationship between the units of measurements.

How to use the charts
First identify the initial unit on the first column. Once the unit is identified, we identify the unit we want to convert to at the top of the chart. Now look for where those two intercept and the multiplier will be the result.
E.g.: If I was initially given grams and wanted to convert to kilograms I would first find the gram row on the first column (which is the third row from the top). Keeping my finger (or mouse) on that row I would then move across until I was in the kilogram column (according to the top of the chart). To convert from grams to kilograms, I would multiply my initial mass by 0.001.

Mass Conversion in the Metric System

	Milligram (mg)	Gram (g)	Kilogram (kg)
Milligram (mg)	1	0.001	0.000001
Gram (g)	1000	1	0.001
Kilogram (kg)	1,000,000	1000	1
