There are 106 pmol in a umol and 103 ul in a ml pmol/ul = (pmol/umol) * (umol/ml) * (ml/ul) = 106 * (umol/ml) * 10-3 = 103 * (umol/ml) That is, multiply the value by 103 = 1000.
Multiply the number in mg by 1,000 to get the same weight in micrograms (ug)
1000 microlitres = 1 milliletre. 25 uL = 0.025 mL
Just multiply by 1000.
One mL equals 1000µl
A normal red blood cell count is about 5,000,000 per uL. There are 1,000 uL per ml and 5 ml per tsp so: 5x10^6 x 10^3 x5 = 25x10^9 or 25,000,000,000 or 25 trillion.
You need to add the 50ul stock solution to 1200ul of distilled water to produce 1250ul of solution with a concentration of 2ul per ml.
There are 1000 microlitres in a millilitre. To convert here, you multiply by 1000. 0.0036 ml x 1000 is 3.6 microlitres.
3mL = 3000µL
300mL is 300,000µL
The conversion is 1000 ul/ mL
2 microliters = 0.002 milliliter
