Just multiply by 1000.
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.
There are 1000 microlitres in a millilitre. To convert here, you multiply by 1000. 0.0036 ml x 1000 is 3.6 microlitres.
To convert milligrams (mg) to micrograms (ug), you need to multiply by 1000 because there are 1000 micrograms in a milligram. To convert milliliters (mL) to microliters (uL), you also multiply by 1000 because there are 1000 microliters in a milliliter. So, to convert 40 mg/mL to ug/uL, you would multiply by 1000 x 1000 = 1,000,000. This means 40 mg/mL is equal to 40,000 ug/uL.
0.93log10 copies per ul (microliter) corresponds to 8.5 copies per ul or 8500 copies per ml. The number is based on powers of 10. This is because 100.93=8.5. So 1 log 10 is 10 copies, 2 log10 is 100 copies, 3log10 is 1000 copies and 6 log10 is 1,000,000 copies. It is reported this way because any treatment needs to show a drop in viral load by a factor of 100s or even 1000s to be effective.
0.001 milliliter per microliter.
Divide by 1000. So 200 microlitres = 0.2 millilitres
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.
That'll be 5,250mL (as one milliliter is one-thousandth of a liter).
1milliliter = 0.001 microliter
Milliliters x 1,000 = microliters (µl)250 x 1,000 = 250,000µl
The conversion is 1000 ul/ mL
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.
