The giant swallowtail is the largest butterfly in the united states . its wingspan can be as large as 16 centimeters. what is the maximum wingspan in millimeters?

The maximum wingspan in millimeters would be 160.

The prefixes, Kilo, Hecto, Deca, Deci, Centi, and Milli all increase by powers of ten. An easy way to remember this is 

King  Kilo
Henry  Hecto 
Died  Deca
Drinking  Deci
Chocolate Centi
Milk   Milli 

Since Centi is greater than Milli by one space, you increase by ten, which means you move the decimal once to the right. 

Hope this helps! :)

160 : You Are Converting Centimeters To Millimeters So Multiply By 100.
Hope This Helps! :)

Iam pretty sure its a sorry if im wrong
