About these units
Cubic Kilometer (km³)
A cubic kilometer represents one billion cubic meters, making it a colossal volume unit used in geology, hydrology, glaciology, and planetary science. Large lakes, ice sheets, magma chambers, and atmospheric water content are often measured in km³. Earth's total ocean volume—about 1.335 billion km³—illustrates the unit's utility in describing planetary-scale systems. The km³ gives scientists a manageable number when dealing with natural features too massive for cubic meters or liters to express conveniently.
Nanoliter (nL)
A nanoliter equals 10⁻⁹ liters and is commonly used in molecular biology, PCR (polymerase chain reaction), and analytical chemistry. Reaction volumes in high-throughput screening and micro-assays are frequently in nanoliters to conserve expensive reagents. In environmental science, trace samples of pollutants or micro-droplets in aerosols may be measured in nanoliters. Nanoliter volumes also arise in precision drug delivery systems and biomedical implants. The nanoliter represents a critical compromise between practical handling and microscopic precision, making it a cornerstone of modern microfluidic research.
