About Fathoms
A fathom (ftm) is equal to 6 feet or 1.8288 meters, traditionally based on the span of a man's outstretched arms. This unit has been used for centuries in maritime navigation to measure water depth and rope or cable lengths. While largely replaced by meters in modern nautical charts, fathoms remain in use by sailors and in naval traditions. The Mariana Trench, Earth's deepest point, reaches about 6,000 fathoms. The term 'to fathom' meaning 'to understand' derives from this nautical unit.
About Picometers
A picometer (pm) is one trillionth of a meter (10⁻¹² m), making it 1,000 times larger than a femtometer but still unimaginably small. This unit is crucial in atomic and molecular physics, as it represents the scale of atomic radii and chemical bonds. For example, a hydrogen atom has a radius of about 53 picometers, and the length of a typical chemical bond ranges from 100 to 200 picometers. X-ray wavelengths also fall within this range.
