To convert from cubic centimeters (cc) to cubic inches (ci), you can use the following conversion factor:
1 cc = 0.0610237 cubic inches
This conversion factor allows you to convert the displacement measurement of a motorcycle engine from cubic centimeters to cubic inches. Simply multiply the number of cubic centimeters by 0.0610237 to obtain the equivalent value in cubic inches.
For example, if you have a motorcycle engine with a displacement of 150 cc, you can convert it to cubic inches as follows:
150 cc * 0.0610237 ci/cc = 9.15355 cubic inches
So, a 150 cc motorcycle engine would have a displacement of approximately 9.15355 cubic inches.
