Zero - 7 feet 8 inches is a linear measurement (length of a line), while square meters are used to measure area (like, uh, squares). If you mean 7 square feet, 8 square inches, you can estimate this fairly easily - one meter is about 3.3 feet, so one square meter is about 3.3 * 3.3 = 10.89 square feet. So 7 square feet, 8 square inches (using a square inch = 1/144 of a square foot) would be 7 + 8/144 square feet, or 7.056 square feet. Divide this by 10.89 square feet per meter, and you get 7.056 / 10.89 = about 0.65 square meters. If you mean a square that's 7 feet 8 inches by 7 feet 8 inches, on the other hand, that's about 58.83 square feet, or about 5.4 square meters.
