> inches/feet/yards ... more convenient for daily use only because that is what you are accustomed to because I grew up with metric, m/cm are much more convenient for daily use I will allow that a "foot" is useful as an approximate intermediary unit between m and cm > Inches/feet being base 12 divides better into thirds and fourths, which is very useful in construction. again only because the US construction industry grew up using fractions instead of decimals
