mikrolitra

Mikrolitra, known in English as microliter, is a unit of volume in the metric system equal to one millionth of a liter (10^-6 L). It is exactly 0.001 milliliters (mL) and, equivalently, 1 cubic millimeter (mm^3). The standard symbol is µL; ASCII representations such as uL are also used in software and older texts.

Relation to other units: 1 mL = 1000 µL; 1 µL = 1000 nanoliters (nL). This makes the microliter a convenient unit for measuring small volumes commonly encountered in laboratory work.

Usage: Microliters are routinely used to measure small volumes of liquids in laboratory settings, including biology, chemistry, and medical testing. They are dispensed with micropipettes and automated liquid handling systems, where precision and accuracy are essential for experimental results.

Measurement and standards: The microliter is an SI-derived unit recognized for scientific use. In practice, measurements are made with calibrated instruments and reported with appropriate uncertainty, often traceable to national or international standards.

Origin and naming: The term derives from the micro- prefix meaning small and the liter. It is widely used across science, medicine, and industry to express small liquid quantities and to facilitate precise experimental protocols.
