    There are 10 millimeters (mm) to 1 centimeter (cm).

    129 cm * (10 mm / cm) = 1290 mm

    Notice how the cm dimensions cancel each other to give dimensions in mm. Setting up the calculation to be a product in numerator/denominator fashion helps you to arrive at correct determinations.

    10 mm make a cm so just multiply by ten to get what your asking or in the reverse divide by ten to get mm to cm.

    so 129 x 10 =1290mm
