1.25×10^−10 by 2.5×10^−8 millimeters
1.25×10^−6 by 2.5×10^−4 millimeters
1.25×10^−11 by 2.5×10^−9 millimeters
1.25×10^−5 by 2.5×10^−3 millimeters
To convert the dimensions from meters to millimeters, we need to multiply each dimension by 1,000.
1.25×10^−8 meters wide becomes: (1.25×10^−8) * 1,000 = 1.25×10^−8 * 10^3 = 1.25×10^−5 millimeters wide.
2.5×10^−6 meters long becomes: (2.5×10^−6) * 1,000 = 2.5×10^−6 * 10^3 = 2.5×10^−3 millimeters long.
Therefore, the dimensions in millimeters are 1.25×10^−5 by 2.5×10^−3 millimeters.
