1 m = 3.28084 ft

Length convert within the family only. Results are floating-point — display rounds to 6 significant digits (the temperature reference note shows why that honesty matters). Definitions are exact where treaties make them exact (foot, pound, nautical mile); calendar units are Gregorian averages.
