    The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres (⁠ 1 100 ⁠ m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.

    Negative aspect ratio is the image ratio determined by the ratio of the gate dimensions multiplied by the anamorphic power of the camera lenses (1× in the case of spherical lenses). [1] Gate dimensions are the width and height of the camera gate aperture, and by extension the film negative frame.

    For comparison, the ratios are also given as a decimal number, which is the flag width divided by its height (e.g. a 2:3 flag has a decimal ratio of ⁠ 3 / 2 ⁠ = 1.5). Flags with irrational ratios have only a decimal approximation, and have the exact form given in the "Notes" column (which also includes additional information such as similar ...
