Home/Pharmacy Technician Certification Exam Review/12 Standard Measurements of Weight, Volume & Length

Weight

Unit Abbr. 1 Unit is Equivalent to
kilogram kg 1,000,000,000,000 ng = 1,000,000,000 mcg
= 1,000,000 mg = 1,000 g
gram g / gm 1,000,000,000 ng = 1,000,000 mcg
= 1,000 mg = 0.001 kg
milligram mg 1,000,000 ng = 1,000 mcg = 0.001 g = 0.000001 kg
microgram mcg 1,000 ng = 0.001 mg= 0.000001 g = 0.000000001 kg
nanogram ng 0.001 mcg = 0.000001 mg
= 0.000000001 g = 0.000000000001 kg

Volume

Unit Abbr. 1 Unit is Equivalent to
liter L / l 1,000 mL = 1,000 cc
deciliter dL / dl 100 mL = 0.1 L = 100 cc
milliliter mL / ml 0.001 L = 1 cc
cubic centimeter cc 1 mL = 0.001 L

Length

Unit Abbr. 1 Unit is Equivalent to
kilometer km 1,000,000 mm = 100,000 cm = 1,000 m
meter m 1,000 mm = 100 cm = 0.001 km
centimeter cm 10 mm = 0.01 m = 0.00001 km
millimeter mm 0.1 cm = 0.001 m = 0.000001 km
