àï6.5èMetric Measurements of Mass.
äèPlease convert the following Metric Measurements of
êê Mass.
âêêConvert .55 g to _____ mg.
êêïkgè hgè dagè gè dgè cgèmg
#êêêêê└────────────────┘
è This conversion involves moving the decimal point three places to
è the right.êèThus, .55 gè =è 550 mg.
éSïThe Metric Measurements of Mass are milligram, centigram,
decigram, gram, decagram, hectogram, and kilogram.ïThe
equivalencies between ç units of Mass are as follows:
êêë1 kilogram (kg)è =è 1000 grams (g)
êêè 1 hectogram (hg)è =è 100 g
êêè 1 decagram (dag)è =è 10 g
êêêè1 gram (g)è =è 1 g
êêë1 decigram (dg)è =è .1 g
êêè 1 centigram (cg)è =è .01 g
êêè 1 milligram (mg)è =è .001 g
ëIt is possible to convert .55 g to mg by using proportions, but it
is much faster to just move the decimal point as was done with Metric
Measurements of Length.ïThe first thing to do is to list the units of
Mass from largest to smallest.
êè kgè hgè dagè gè dgè cgè mg
#êêêêï└─────────────────┘
Since each unit of measurement differs from the next unit by a factor of
10, converting grams to milligrams involves moving the decimal point
three places to the right.
êêêThus, .55 gè=è550 mg.
