How do I convert RM per square foot to RM per square metre?

Multiply by 10.7639. RM 300 per ft² is RM 3,229 per m². Going the other way, divide: RM 3,000 per m² is RM 279 per ft².

How many square feet in an acre, and how many acres in a hectare?

43,560 square feet in an acre, which is 4,046.86 square metres. A hectare is 10,000 square metres, or 2.4711 acres. Older Malaysian land titles are in acres, roods and poles: 4 roods to the acre, 40 poles to the rood.
