Metric System Worksheet
Meter (m), liter (L), or grams (g) = 1 (no zeros)
Centimeters (cm), centiliter (cl), centigram (cg) = 100 (2 zeros)
Millimeters (mm), milliliter (ml), milligrams (mg), kilograms (kg), or kilometers (km) = 1,000 (3 zeros)
microns (µm), micrometers (µm), microliters (µl), micrograms (µg or mcg) = 1,000,000 (6 zeros)
1. First ask yourself how many zeros there are in each unit, then subtract them. That is the
number of places you need to move the decimal point.
2. Then ask yourself if the given unit is smaller or larger than the units in the answer.
When you start with a larger unit, move decimal point to the right.
When you start with a smaller unit, move decimal point to the left.
To get cm, multiply inches by 2.54
To get inches, divide cm by 2.54
To get pounds (lbs), multiply kg by 2.2
To get kg, divide pounds by 2.2
°C = (_____ - 32) x 0.5556
°F = (______ x 1.8) + 32
10 mm = 1 cm
10 m = 0.010 km
10 cm = 100 mm
10 g = 10,000 mg
10 m = 1000 cm
10 mg = 0.010 g
10 cm = 0.1 m
10 ml = 0.010 L
10 m = 10,000 mm
10 L = 10,000 ml
10 mm = 0.010 m
10 inches = 25.4 cm
10 µm = 0.000010 m
10 cm = 3.937 inches
10 m = 10000000 µm
10 lbs = 4.545 kg
10 µm = 0.0010 cm
10 kg = 22 lbs
10 cm = 100,000 µm
10 °F = -12.22 °C
10 km = 10,000 m
10 °C = 50 °F
