Methyl cation, anion, and radical. Methyl cation. The methylium cation (CH3+) exists in the gas phase, but is otherwise not encountered. Some compounds are considered to be sources of the CH3+ cation, and this simplification is used pervasively in organic chemistry.
The square foot (plural square feet; abbreviated ft 2 or sq ft) is an imperial unit and U.S. customary unit (non-SI, non-metric) of area, used mainly in the United States and partially in Canada, United Kingdom, Hong Kong, Bangladesh, India and Pakistan. It is defined as the area of a square with sides of 1 foot.
To find the number of square meters in 100 square feet requires using the following formula: feet squared divided by 10.764 square feet per square meter. The solution then is 100 square feet divided by 10.764 square feet per square meter equals 9.29 square meters. Both square feet and square meters are units used to measure area. Square feet is the unit used most often in the United States, while square meters is more commonly used internationally.
