457 millimetres
45 mm
45 mm = 4.50 cm
45 cm
Both measurements are equivalent; 45 cm is equal to 450 mm since 1 cm equals 10 mm. Therefore, 45 cm is not bigger than 450 mm; they represent the same length.
45 mm Algebraic Steps / Dimensional Analysis Formula 4.5 cm*10 mm 1 cm=45 mm
45 mm 1 cm = 10 mm 1 mm = 0.1 cm
There is 10 mm in one cm so you multiply the cm value by 10 to get the mm value Example 12 cm will be 12x10=120 mm
45 mm = 4.5 cm
62mm
1mm = 0.1cm 45mm = 4.5cm
To decrease centimeters (cm) by millimeters (mm), you need to remember that 1 cm is equal to 10 mm. To subtract mm from cm, first, convert the cm to mm by multiplying the cm value by 10. Then, subtract the desired mm value from this total. Finally, if needed, convert back to cm by dividing by 10.
1 cm = 10 mm 1 mm = 0.1 cm
