There are 1,550 square inches in a square meter. In order to convert square meters into square inches, two conversion factors need to be applied.
The first conversion is changing square meters into square centimeters. One meter is equivalent to 100 centimeters, so one square meter is the same as 10,000 square centimeters.
The second and final conversion is changing the square centimeters into square inches. There are 2.54 centimeters per inch, so the 10,000 square centimeters needs to be divided by 2.54 two times. This gives 1,550 square inches.
To convert square meters directly into square inches, simply multiply the square meters by 1,550 square inches to reach the same answer.
