Direction: mL → µL
Tip: 1 mL equals 1,000 µL. Enter either field.
Formula used
The microliter is 10−6 liters and the milliliter is 10−3 liters. Therefore:
µL = mL × 1,000 and mL = µL ÷ 1,000
Both units are volume. Conversion is exact by definition in the SI system.

FAQs
By definition, 1 mL = 1,000 µL. This follows from SI prefixes: milli = 10−3, micro = 10−6. Therefore a milliliter contains one thousand microliters.
Yes. Enter either mL or µL. The other field updates instantly without additional clicks, keeping values synchronized according to the formula.
Choose Round for conventional rounding, or Floor/Ceil to bias low/high. Decimal places control displayed precision only; internal math uses double precision.
