A 9x12 rug is 108 × 144 inches — 274 × 366 cm, or 108 square feet. That is big enough for a large living room, a king bed, or a dining table for six to eight.

The arrow marks the 9 × 12 ft. All conversions are exact from the nominal feet: a foot is 12 inches and 30.48 centimeters. Actual woven rugs vary by an inch or two between makers, so measure if it has to fit a specific gap.
The conversion is arithmetic, not a lookup. A foot is 12 inches, so 9 × 12 ft is 108 × 144 in. A foot is 30.48 centimeters, so it is 274 × 366 cm — about 10.0 square meters. Multiply and check; nothing here has to be taken on trust.
What it is actually big enough for. The size that goes under a king bed properly, and the one a large living room needs for all the furniture legs to sit on it. It needs a room of about 11 × 14 ft to leave floor showing at the walls.
How it compares. Half again the area of an 8 × 10. Twice the area of a 6 × 9.
Nominal is not exact. "9 × 12 ft" is the name of a size class, not a guaranteed measurement. Woven and tufted rugs come off the loom a little under or over, and hand-knotted rugs vary more. If the rug has to fit between two fixed things, measure the actual piece.
108 × 144 inches. A foot is 12 inches, so 9 ft is 108 in and 12 ft is 144 in.
274 × 366 centimeters, because a foot is exactly 30.48 cm. That is about 10.0 square meters.
108 square feet — 9 multiplied by 12.
The size that goes under a king bed properly, and the one a large living room needs for all the furniture legs to sit on it. It needs a room of about 11 × 14 ft to leave floor showing at the walls.
Close, but not guaranteed. Rug sizes are retail conventions rather than a standard, and a rug sold as 9 × 12 ft can measure an inch or two either way. Measure the actual rug if it has to fit a specific space.
