It depends what it is dropping from and a few other things. a drop is irreproducible so you cannot get an answer really. I can definitely say 1ul is smaller than your common drop
1,000,000ul
500 micro litre
A million.
There are 500,000 micro liters in 0.5 liter.
1000000
10
that is a comparison between weight and volume... you need to check the density of what you're measuring (water is 1000g/1L, but salt water is different) and do the correct unit conversion. micro-liters are x10^-6
1000 times greater. The prefix "milli" denotes 1/1000 of a measure.
129 (grams per liter) = 129,000,000 micrograms per liter.
There are 10 deciliters of water in a liter of water.
1,000,000 (one million)Micro means millionth. 1 microliter is 1 millionth of a liter. There are therefore 1 million microliters in a liter.
how many cups of water in a liter
