Final answer:
To convert a 26-inch bike wheel diameter to millimeters, multiply by the conversion factor of 25.4 mm per inch, resulting in a diameter of 660.4 mm.
Step-by-step explanation:
To convert the diameter of a bike wheel from inches to millimeters, we can use the conversion factor that 1 inch is equal to 25.4 millimeters. The conversion formula is as follows:
Diameter in millimeters = Diameter in inches × Conversion factor
Now, we can substitute the given values into the formula:
