Unit Conversion Principle (Dimensional Analysis) $Q_{\text{original}} \times \frac{\text{Desired Unit}}{\text{Original Unit}} = Q_{\text{desired}}$ To convert a quantity from one unit to another, multiply the quantity by a conversion factor that has the desired unit in the numerator and the original unit in the denominator. This ensures the original unit cancels out, leaving the desired unit. Common Customary Length Conversions $1 \text{ foot} = 12 \text{ inches}$ $1 \text{ yard} = 3 \text{ feet}$ $1 \text{ mile} = 5280 \text{ feet}$ These are fundamental relationships for converting between customary units of length. Common Customary Weight Conversions $1 \text{ pound} = 16 \text{ ounces}$ $1 \text{ ton} = 2000 \text{ pounds}$ These are fundamental relationshi...
