There are a thousand micro-liters in a milliliter.
there are 1,000,000 microlitres (ul) in a litre, so the answer to this is that there is 25,000,000ul in 25 litres
I don't recognise these units: 1. mM - do you mean millimeters, which should be written mm? 2. ul - l is used for liters, but u? In any case millimeters is a length and liters is a volume, they are not convertible -- The person is using metric system, in which they are convertible. Cubic mm to microliters (uL). i believe that one cubic millimeter is the same as cubic centimeters by 10^-3 so 1 mm = .001 cm^3 (cubic centimeters) -- mM is milliMolar and uL is microlitre
1/1000 liters
1000 microlitres = 1 milliletre. 25 uL = 0.025 mL
1
1 liters = 1000000 microliters
1 dl = 0.1 liters
1 US cup is 0.2365 liters.
1 US Quart = .95 liters 1 UK quart = 1.14 liters
1 (cubic kilometer) = 1 trillion liters.
3.785 liters = 1 gallon.
