A metric SI-prefix conversion — “micro” means one millionth, commonly needed in laboratory and pharmaceutical dosing.
How it works
Multiplying milliliters by 1,000 gives microliters; dividing microliters by 1,000 gives milliliters back. Type into either field and the other updates instantly.
What this does not include
This does not include mass-based conversions — for converting to a weight in milligrams or micrograms, use this site’s density-based converters instead.
How to use this calculator
- Enter a value in either milliliters or microliters — the other field fills in automatically.
Frequently asked questions
Where is this conversion most commonly needed?
Laboratory pipetting, drug dosing, and any small-volume scientific measurement where microliters are the standard working unit.
How small is a microliter?
One millionth of a liter — about the size of a small droplet, far too small to measure with a standard kitchen measuring tool.
Is “µL” the same as “uL”?
Yes — “uL” is commonly used in plain text as a substitute for the Greek mu symbol (µ) in “µL,” both meaning microliter.
