About Foot (ft)
An imperial unit of length equal to 12 inches (0.3048 meters exactly). Although most countries have moved to the metric system, the foot remains the international aviation standard for altitude — flight levels are quoted in hundreds of feet worldwide — and is the primary unit in US construction blueprints, real estate listings, surveying, and everyday height measurement in the US and UK. A foot divides into 12 inches and three feet make a yard, reflecting the base-12 heritage of English measurement.
About Millimeter (mm)
A metric unit of length equal to one thousandth of a meter (0.001 m), about the thickness of a credit card. Millimeters are the default unit in mechanical engineering drawings, manufacturing tolerances, rainfall measurement, and precision machining. Camera focal lengths, bullet calibers (outside the US), and tire dimensions are routinely quoted in millimeters because the unit sits right at the edge of what the human eye can distinguish unaided.
