Study Notes

Metric System

The metric system uses the following prefixes: Kilo, Hecto, Deka, UNIT, Deci, Centi, Milli.
The metric system is used to measure: meters (length), liters (volume), grams (mass).

Length

1 inch (in) = 2.54 centimeters (cm)
1 foot (ft) = 30.48 cm = 0.3048 meters (m)
1 yard (yd) = 91.44 cm = 0.9144 m
1 mile (mi) ≈ 1.61 kilometers (km)
1 millimeter (mm) ≈ 0.03937 in
1 centimeter (cm) ≈ 0.3937 in
1 meter (m) ≈ 1.0936 yd = 3.2808 ft
1 kilometer (km) ≈ 0.6214 mi
1 foot (ft) = 12 inches (in)
1 yard (yd) = 3 ft
1 yard (yd) = 36 in
1 mile (mi) = 5280 ft
1 mile (mi) = 1760 yd

Area

1 square foot (ft2) = 144 square inches (in2)
1 square yard (yd2) = 9 ft2 = 1296 in2
1 square mile (mi2) = 27,878,400 ft2 = 3,097,600 yd2
1 acre = 43,560 ft2
1 square mile (mi2) = 640 acres
1 square inch (in2) ≈ 6.45 cm2
1 square foot (ft2) ≈ 0.093 m2
1 square yard (yd2) ≈ 0.836 m2
1 square mile (mi2) ≈ 2.59 km2

1 cubic yard (yd3) ≈ 201.97 gal
1 gallon (gal) ≈ 231 in3
1 cubic foot (ft3) of fresh water ≈ 62.5 lb
1 cubic foot (ft3) of salt water ≈ 64 lb
1 cubic centimeter (cm3) = 1 milliliter (mL) = 1 gram (g) = 1000 mm3
1 cubic decimeter (dm3) = 1000 cm3 = 1 liter (L) = 1 kilogram (kg)
1 cubic meter (m3) = 1000 dm3 = 1 kiloliter (kL) = 1,000 L
1 liter (L) ≈ 1.06 qt
1 gallon (gal) ≈ 3.7854 L
1 quart (qt) ≈ 0.9464 L
1 ounce (oz) ≈ 29.5735 mL

Weight

1 pound (lb) = 16 ounces (oz)
1 ton (T) = 2,000 lb
1 ton (T) ≈ 0.9072 metric ton (t)
1 kilogram (kg) = 1000 grams (g)
1 metric ton (t) = 1,000 kg
1 kilogram (kg) ≈ 2.2 lb
1 ounce (oz) ≈ 28 g

Time

1 minute (min) = 60 seconds (sec)
1 hour = 60 min
1 day = 24 hours
1 year = 365 days

Percentage

To find a percentage, divide the part by the whole and multiply by 100.
Percentage = Rate * Base
