1: Standard size of a 5-room HDB unit
The standard size of a 5-room HDB unit is 110 square meters (m2).
1 square foot (ft2) is equal to exactly 0.092 903 04 m2.
100 m2 is greater than ROUNDDOWN(100 / 0.09290304, 0) = 1,076 ft2
120 m2 is greater than ROUNDUP(120 / 0.09290304, 0) = 1,292 ft2
Therefore we can clearly say that a 5-room HDB flat is between 1,076 and 1,292 ft2.
