Measuring liquid medicine accurately
- Use the oral syringe, dropper or cup supplied with the medicine — household spoons are not standardized.
- "tsp" (teaspoon) and "tbsp" (tablespoon) are easy to confuse; a mix-up is a threefold error. mL avoids it.
- 1 mL = 1 cc — see mL to cc. Converting drops? See drops to mL.
