When a barn (a very small unit of area used for measuring the cross sectional area of atomic nuclei) is multiplied by a megaparsec (a very large unit of length used for measuring the distances between galaxies), the result is a human-scaled unit of volume approximately equal to 2 ⁄ 3 of a teaspoon (about 3 mL).

YouTube's intent in the creation of YouTube Shorts in 2020 was to compete with TikTok, [4] an online video platform for short clips. The company started by experimenting with vertical videos up to a length of 30 seconds in their own section within the YouTube homepage. [5] This early beta was released only to a small number of people.
Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.The microwave is in-between 1 meter to 1 millimeter.. A centimetre or centimeter (US/Philippine spelling), with SI symbol cm, is a unit of length in the International System of Units (SI) equal to one hundredth of a metre, centi being the SI prefix for a factor of 1 / 100 .

In the People's Republic of China, since 1984, the chi has been defined as exactly 1/3 of a metre, i.e., 33 + 1 ⁄ 3 cm (13.1 in). However, in the Hong Kong SAR the corresponding unit, pronounced tsek (cek3) in Cantonese, is defined as exactly 0.371475 m (1 ft 2.6250 in) or 1 7/32 ft. [2] The two units are sometimes referred to in English as "Chinese foot" and "Hong Kong foot".
Reciprocal length or inverse length is a quantity or measurement used in several branches of science and mathematics, defined as the reciprocal of length. Common units used for this measurement include the reciprocal metre or inverse metre (symbol: m −1 ), the reciprocal centimetre or inverse centimetre (symbol: cm −1 ).
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
