    1 047.35 M J (Jupiter mass) It is also frequently useful in general relativity to express mass in units of length or time. M ☉ G / c 21.48 km (half the Schwarzschild radius of the Sun) M ☉ G / c 3 ≈ 4.93 μs; The solar mass parameter (G·M ☉), as listed by the IAU Division I Working Group, has the following estimates: [20]

    Coins of one euro (7.5 grams), [63] one U.S. dollar (8.1 grams) [64] and one Canadian loonie (7 grams [pre-2012], 6.27 grams [2012-]) [65] 10 −2 decagram (dag) 1.2 × 10 −2 kg Mass of one mole (6.02214 × 10 23 atoms) of carbon-12 (12 grams) 1.37 × 10 −2 kg Amount of ethanol defined as one standard drink in the U.S. (13.7 grams) [66] 2 ...

    en.wikipedia.org/wiki/Discrete_Fourier_transform

    Thus, the specific case of = = / is known as an odd-time odd-frequency discrete Fourier transform (or O 2 DFT). Such shifted transforms are most often used for symmetric data, to represent different boundary symmetries, and for real-symmetric data they correspond to different forms of the discrete cosine and sine transforms.

    This amounted to 34.1% of all seaborne trade for the year. [4] Combining the amount carried with the distance it was carried, oil tankers moved 11,705 billion metric-ton-miles of oil in 2005. [63] By comparison, in 1970 1.44 billion metric tons of oil were shipped by tanker. [64] This amounted to 34.1% of all seaborne trade for that year. [65]

  6. Multiplication table - Wikipedia

    en.wikipedia.org/wiki/Multiplication_table

    In mathematics, a multiplication table (sometimes, less formally, a times table) is a mathematical table used to define a multiplication operation for an algebraic system. The decimal multiplication table was traditionally taught as an essential part of elementary arithmetic around the world, as it lays the foundation for arithmetic operations ...

    en.wikipedia.org/wiki/TNT_equivalent

    A type Ia supernova explosion gives off 12 × 10 44 joules of energy, which is about 2.4–4.8 hundred billion yottatons (24–48 octillion (2.4– 4.8 × 10 28) megatons) of TNT, equivalent to the explosive force of a quantity of TNT over a trillion (10 12) times the mass of the planet Earth.

    The ratio of width to height for a traditional television screen is 4:3, or about 1.33:1. High-definition televisions use an aspect ratio of 16:9, or about 1.78:1. The aspect ratio of a full 35 mm film frame with soundtrack (also known as the Academy ratio ) is 1.375:1.
