PLEASE EXPLAIN THE DIFFERENCE BETWEEN CM AND MM

I HAVE WRITTEN MANY TIMES THIS WEEKEND TRYING TO UNDERSTAND WHAT IS GOING ON WITH MY BODY(OVARIES/CERVIX)...SORRY FOR CAPS..EYES NOT SO GOOD RIGHT NOW..I HAVE LOOKED ALL OVER TO FIND WHAT THE DIFFERENCE IS BETWEEN CM AND MM IN MEASURES CYSTS AND MASSES...I WAS FOUND TO HAVE 8MM CYST CERVIX THAT HAS A HYPOECHOIC AREA WITH BLOOD FLOW MEASURING 5.5MM. MY UTERUS IN TOTAL MEASURES 5.55CM X 3.13CM X 3.67CM. NO FREE FLUID IS SEEN..THIS WAS FOUND ON A INTERNAL ULTRA SOUND ALONG WITH THE FOLLOWING..
MY RIGHT OVARY MEASURES 3.1CM X 2.65CM X 1.06CM AND HAS A "SOLID COMPONENT" THAT MEASURES 1.54CM X 1.2CM X 1.59..
MY LEFT OVARY MEASURED 1.85CM X 180CM X 1.31. NO OTHER COMMENTS ON THE RADIOLOGY REPORT ABOUT THAT OVARY..
I AM SCHEDULED FOR A C-SCAN TOMORROW..I WOULD LIKE TO KNOW WHAT THESE MEASUREMENTS MEAN..IS CM BIGGER MM OR THE OTHER WAY AROUND? I AM TRYING TO TAKE IN AS MUCH INFO AS I CAN BEFORE TOMORROW..ANY IDEAS OR EXPLANATIONS WOULD BE GREATLY APPRECIATED..THANKS..SUZY
