                                                                                          rennywoman (20)
                                                            
                          
                          
                                                          There are ten millimeters in a centimeter, so you merely have to multiply by ten. The secret to understanding the metric system is to simply memorize the units of measurements. There are 100 centimeters in a meter, 10 millimeters in a centimeter, and 1000 meters in a kilometer. I hope this helps.
