Nanometer
A nanometer (nm) is an incredibly small unit of length in the metric system. It equals one-billionth of a meter (0.000000001 meters). Nanometers are used to measure things at the atomic and molecular scale, like the size of viruses, DNA strands, or the width of a few atoms. The symbol for nanometer is "nm". This unit is essential in fields like nanotechnology, physics, and chemistry, where scientists work with materials and particles too tiny to see with regular microscopes. Understanding measurements in nanometers helps researchers develop new materials, medicines, and electronic devices.
Ken
A ken is a traditional Japanese unit of length used mainly in architecture and construction. It measures the distance between two pillars in traditional Japanese buildings and is roughly equivalent to 6 Japanese feet (shaku) or about 1.82 meters (approximately 6 feet).
The ken was a standard module in Japanese design, influencing room sizes and proportions in temples, houses, and other structures. Its use helped maintain harmony and consistency in traditional building layouts.
Though largely replaced by the metric system today, the ken remains significant in studying traditional Japanese architecture and cultural heritage.
