1 ft is EXACTLY 0.3048 m, 7 ft are EXACTLY 2.1336 m (7*12*25.4/1000) I guess your choices are: * 7 ft (four digits, no direct calculations possible due to "text") * 2.1336 (six digits, no unit "m" required, exact match) * 2.14 (4 digits, rough conversion, may use exact back conversion by matching rounding) Since there are many other definitions of foot, apart of this international foot (ranging from 0.25 m up to 0.3333333333333... m), I do not see a problem by rounding to two decimal digits. AFAIK any numbers with units "ft" and "mph" will be converted to metric units. -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS.
