Approximately how many grams does 1 microliter of water weigh?

Explanation:
Converting small volumes to mass using density. Water has a density of about 1 g per milliliter, so 1 mL weighs roughly 1 g. A microliter is one thousandth of a milliliter, so its weight is one thousandth of a gram. In math terms: 1 µL × (1 g / 1 mL) × (1 mL / 1000 µL) = 0.001 g. So, 1 microliter of water weighs approximately 0.001 g, with only tiny variations due to temperature or pressure.
