E.G. 1.4cm x1.4cm
Basically turn it into mm
140 X 140 =19,600
Then take away two 0 away and thats your answer
multiply by 2.54
Centimetres to inches: divide by 2.54. Inches to centimetres: multiply by 2.54.
multiply by 2.54
Multiply centimeters by 100.
Multiply the number of inches by 2.54.
Centimetres to metres: divide by 100 Centimetres to millimetres: multiply by 10 Centimetres to kilometres: divide by 100000.
There are 30.48 centimetres in one foot. Therefore, to convert feet to centimetres, multiply by 30.48. For example, 4 feet is equal to 4 x 30.48 = 121.92 centimetres.
There are 160934.4 centimetres in one mile. Therefore, to convert miles to centimetres, multiply by 160934.4. For example, 5 miles is equal to 5 x 160934.4 = 804672 centimetres.
You multiply (by 10) when changing from centimetres/cm to millimetres/mm.
There are 100 centimetres in one metre. Therefore, to convert from metres to centimetres, multiply by 100. In this instance, 31.4 x 100 = 3140 centimetres.
One kilometre is equal to 100,000 centimetres. Therefore, to convert kilometres to centimetres, multiply by 100,000.
Divide by 1,000.
