To convert the dimensions from meters to millimeters, we need to multiply them by 1000 since there are 1000 millimeters in 1 meter.

The width is 1.25 x 10^-8 meters, which is equal to 1.25 x 10^-8 x 1000 millimeters (since 1 meter = 1000 millimeters). This can be simplified as 1.25 x 10^-8 x 10^3 millimeters.

Simplifying further, we can add the exponents and compute the result: 1.25 x 10^-8 x 10^3 = 1.25 x 10^-8+3 = 1.25 x 10^-5 millimeters wide.

The length is 2.5 x 10^-6 meters, which is equal to 2.5 x 10^-6 x 1000 millimeters. Simplifying, 2.5 x 10^-6 x 10^3 = 2.5 x 10^-6+3 = 2.5 x 10^-3 millimeters long.

Thus, the dimensions in millimeters are approximately 1.25 x 10^-5 millimeters wide by 2.5 x 10^-3 millimeters long.
