converting grams to milligrams and micrograms

These are ounces of weight, not volume (Ounces, especially, are confusing and whether they refer to weight or volume depends entirely on context)

• 1 gram = 1,000,000 micrograms (mcg) = 1.ooo milligrams (mg)
• 1,000 micrograms = one milligram = 0.001 gram
• 1,000 grams = one kilogram (one kilo, kg) = 2.2 pounds (LB, #)
• one pound = 454 grams (g)
• one ounce = 28.35 grams
• 16 ounces = one pound (LB, #)

Measures of volume:

• 3 teaspoons = 1 tablespoon
• 2 tablespoons = 1 ounce = 1/8 cup
• 8 ounces = 16 tablespoons = 1 cup
• 1/2 teaspoon = 2.5 mL (milliliters)
• 1 cup = 240 mL
