Measure of Weight

The gram is the primary unit of weight in the SI. It is the weight of 1 cm³ of water at 4 °C,
its temperature of greatest density.

The table of metric weight:

1 kilogram (kg) = 1000.000 grams
1 hectogram (hg) = 100.000 grams
1 dekagram (dag) = 10.000 grams
1 gram (g) = 1.000 gram
1 decigram (dg) = 0.1000 gram
1 centigram (cg) = 0.010 gram
1 milligram (mg) = 0.001 gram
1 microgram (µg or mcg) = 0.000,001 gram
1 nanogram (ng) = 0.000,000,001 gram
1 picogram (pg) = 0.000,000,000,001 gram
1 femtogram (fg) = 0.000,000,000,000,001 gram

This table may also be written:

1 gram

= 0.001 kilogram
= 0.010 hectogram
= 0.100 dekagram
= 10 decigrams
= 100 centigrams
= 1000 milligrams
= 1,000,000 micrograms
= 1,000,000,000 nanograms
= 1,000,000,000,000 picograms
= 1,000,000,000,000,000 femtograms

Most common weight denominations are:

1000 micrograms (µg or mcg) = 1 milligram (mg)
1000 milligrams (mg) = 1 gram (g)
1000 grams (g) = 1 kilogram (kg)
