Q&A for How to Measure Millimeters

Multiply inches by 2.54 to get centimeters. Multiply inches by 25.4 to get millimeters.

Milligrams are measured by a weight scale. First weigh an empty container. Then put the liquid into the container, and weigh it again. Subtract the weight of the empty container from the weight of the container with the liquid in it. That gives you the weight of the liquid.

(481 mm)(931 mm) = (481 x 0.03937 in)(931 x 0.03937 in) = (18.94 in)(36.65 in) = 694.15 sq in.

Convert linear dimensions to millimeters if necessary, then multiply them together to get square millimeters.

Multiply 36 x 27 x 28, then divide by 16,387.064. The answer will be in cubic inches. Or convert all measurements to inches first, then multiply. There are 25.4mm in an inch.

5/32" is roughly 4 mm, and 15/32" is roughly 12 mm. You need a shredder that shreds to around 1/32" by a bit less than ¼".

Convert each millimeter measurement to centimeters by dividing each number by 10. Then multiply the three new numbers together. Or you could multiply the three mm measurements together, and divide by 1,000. In either case the answer would be in cubic centimeters.

Because one centimeter equals 10 millimeters, 5 cm is 50 mm, and 5 cm 4 mm is 54 mm.

There are many metric units much smaller than a millimeter. See Section 4 of Wikipedia's article on the metric system. The unit closest to 1/64 of an inch is the millimeter. 1/64 inch is about 1.6 millimeters.

(4.4 ft)(304.8 mm/ft) = 1,341.12 mm.

If your measuring tape is calibrated in inches, it may be calibrated in centimeters/millimeters, too. If not, calculate the inch equivalent of 6 mm: 6 mm / 25.4 = 0.236 inch, which is slightly less than a quarter-inch.
