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
There are 500,000 micro liters in 0.5 liter.
10
1000000
1000 times greater. The prefix "milli" denotes 1/1000 of a measure.
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
129 (grams per liter) = 129,000,000 micrograms per liter.
There are 10 deciliters of water in a liter of water.
A liter is one million times greater than a microliter. This is because there are one million microliters in one liter.
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.
There are 1,000,000 micro-liters in one liter. This conversion is based on the prefix "micro-" which denotes one millionth of the base unit.
