According to the Oxford Dictionaries, one millimetre equals 0.039 inch in length. As a result, 25 millimetres equals 25 x 0.039 inches, or 0.975 inches.
The inch to centimetre conversion is the most frequent, with 1 inch equaling 2.54 cm. To put it another way, one centimetre is equivalent to 1/2.54, or 0.39. However, because 1 centimetre equals 10 millimetres, 0.39 should be divided by 10 to get the number of millimetres in 1 inch. The answer is 0.039, which is the same as the Oxford Dictionaries number.
