How many UL are in a mL?
| Microliter [μL] Milliliter [mL] | 20 μL 0.02 mL | 50 μL 0.05 mL | 100 μL 0.1 mL | 1000 μL 1 mL |
|---|
How do you convert UL to L?
Simply put, ul is smaller than l. In fact, a microliter is “10 to the power of -6” smaller than a liter. Since a microliter is 10^-6 smaller than a liter, it means that the conversion factor for ul to l is 10^-6. Therefore, you can
multiply 1 ul by 10^-6 to get 1 ul converted to
l.

white
blood cells, platelets, and plasma. Your white blood cells account for only about 1% of your blood, but their impact is big. White blood cells are also called leukocytes. They protect you against illness and disease.
Are all white blood cells lymphocytes?

A lymphocyte is a
type of white blood cell
that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins.
