This metric system review video tutorial provides an overview / review of how to convert from one unit to another using a technique called dimensional analysis or the factor label method. It shows you how perform conversions with SI units in the metric system and in the english system including units that contain exponents such as squares and cubes. It provides unit conversion practice problems that relates to chemistry, physics, algebra, trigonometry and even pre-calculus. It contains word problems that relates to density, linear & angular speed problems, and even a few sat proportion word problems.
Here is a list of topics:
1. A list / table of SI conversion factors in the english and metric system.
1 L = 1000 ml, 1 Kg = 1000 g, 1 m = 100 cm, 1 ft = 12 in, 3 ft = 1 yd,
1 ml = 1cm^3, 16 oz = 1 lb, 1 m^3 = 1000 L, 1 lb = 453.6 lb,
1 cm = 10 mm, 1 km = 0.6214 mi, 1 in = 2.54 cm, 1 qt = 946 ml
1 gal = 4 qt, 1 gal = 3.785 L, 1 mi = 5280 ft

9. Unit Conversions - Chemistry - Density Word Problems
a) The density of Aluminum is 2.7 g/cm^3. How many kilograms of Aluminum are present in a 2.75 Liter.
b) The density of gold is 19.3 g/cm^3. If the value of gold is $1300 per ounce, how much would it cost to buy a 1.75 Liter sample of gold.
10. Angular Speed & Linear Velocity Trig / Precalculus Problem
a) A car has a linear speed of 35 mph. The radius of its wheels are 8.5 inches each. Calculate the angular speed of each wheel in rpm.
b) A wheel makes one revolution in 125 milliseconds. The radius of the wheel is 9 inches. Calculate the linear speed of the wheel in Km/hr or kilometers per hour.
11. Dimensional Analysis - SAT Word Problems - Proportions
a) If Sally can make 7 cakes in 3 hours, how many cakes can she make in 10 hours?
b) A certain map has the following scale: 1in = 5.5 miles. If the distance between city A and city B is 12.6 inches on the map, what is the distance in miles between the two cities?
