Final answer:
A microliter (µL) is one one-millionth (1/1,000,000 or 10^-6) of a liter (L). This is because there are 1,000 microliters in a milliliter and 1,000 milliliters in a liter, resulting in 1,000,000 microliters per liter.
Step-by-step explanation:
The student has asked about the conversion between microliters and liters. A microliter (µL) is a unit of volume in the metric system, and it is a fraction of a liter (L). In the metric system, conversion between units is often a matter of multiplying or dividing by powers of ten.
There are 1,000 microliters in a milliliter (mL), and there are 1,000 milliliters in a liter. So, to find out how many microliters there are in a liter, we multiply the two conversions together: 1,000 × 1,000, which equals 1,000,000. Therefore, we can state that 1 liter is equivalent to 1,000,000 microliters.
To answer the question directly, a microliter is one one-millionth of a liter, or practically, it is written as a fraction as 1/1,000,000 or 10-6 liters. This is a useful conversion when dealing with small volumes of liquid in fields like chemistry, biology, or medicine, where precise measurements are critical.
