i have area in feet of three rooms

[hussain12345]

but i have to calculate area in meter square as a total area of the property

[sddsddean]

1 sq metre = 10.7643 sq feet, so just multiply by 10.7643.

[Trevilino]

I think he meant divide your answer in sq/ft by 10.7643 to convert your answer to sq/m.

Calculate your area in square feet, then use this site to convert to square meters:
