Confused about inches or grams?

ok I have a banana it's 9" long  and the cc said that it's 149 calories and a 6" long banana ( 101g grams)  it's 90 calories. ok the BIG cuestion it's When I weight my banana my food scale sets at 105 grams but it's 9" long so I have to log my banana in grams or inches? The same happen when I have 2 bananas the same inch long but when i weight them it's a lower grams that the cc said somebody can help me????

Well some 9" bananas will be thicker than others, so just go with what your scale says.

Thanks for you advice I log my banana in grams yesterday it's just that  i  felt so confused about this!! thanks again and have a nice day!!!
