## Quick Reference Formulas & Conversions (Memorize First)
### Fractions & Decimals
| Conversion | How To |
| :--- | :--- |
| Fraction to decimal | Divide numerator ÷ denominator |
| Decimal to percent | Multiply by 100 |
| Percent to decimal | Divide by 100 |
| Percent to fraction | Write over 100, simplify |
### Ratios & Proportions
| Formula | Example |
, 4|Page
| :--- | :--- |
| a/b = c/d → cross multiply: a×d = b×c | 2/3 = 4/6 → 2×6 = 3×4 = 12 |
### Dosage Calculations (Nursing)
| Formula | Equation |
| :--- | :--- |
| Desired dose formula | (Desired ÷ Have) × Vehicle = Amount to give |
| IV flow rate (mL/hr) | Total volume ÷ Total time (hours) |
| IV drop rate (gtt/min) | (Volume × Drop factor) ÷ Time (minutes) |
| Weight-based dosing | Dose (mg/kg) × Weight (kg) = Total dose |
### Essential Conversions (Memorize)
| Metric | Household | Apothecary |
| :--- | :--- | :--- |
| 1 kg = 1000 g | 1 tsp = 5 mL | 1 gr (grain) = 65 mg |
| 1 g = 1000 mg | 1 tbsp = 15 mL | 1 oz = 30 mL |
| 1 mg = 1000 mcg | 1 cup = 240 mL | 1 lb = 16 oz |
| 1 L = 1000 mL | 1 oz = 30 mL | 1 kg = 2.2 lb |
