how many units for 0.50ml?

Answer 1

The conversion from milliliters to units depends on the substance being measured, as "units" can refer to different quantities based on context. For instance, in medicine, units often measure the potency of a drug rather than its volume. Therefore, without additional information on the substance or context, it's impossible to accurately convert 0.50 ml to units. Always refer to specific guidelines or instructions related to the substance in question for precise conversion.
