  2. Tonne - Wikipedia

    en.wikipedia.org/wiki/Tonne

    The tonne (/ t ʌ n / ⓘ or / t ɒ n /; symbol: t) is a unit of mass equal to 1,000 kilograms.It is a non-SI unit accepted for use with SI.It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton (United States customary units) and the long ton (British imperial units).

  3. Orders of magnitude (mass) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(mass)

    An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.

  4. Ton - Wikipedia

    en.wikipedia.org/wiki/Ton

    For practical purposes the displacement ton (DT) is a unit of volume, 35 cubic feet (0.9911 m 3), the approximate volume occupied by one ton of seawater (the actual volume varies with salinity and temperature). [16] It is slightly less than the 224 imperial gallons (1.018 m 3) of the water ton (based on distilled water).

    The metric ton is the name used for the tonne (1000 kg, 2 204.622 62 lb), which is about 1.6% less than the long ton. The US customary system also includes the kip , equivalent to 1,000 pounds of force, which is also occasionally used as a unit of weight of 1,000 pounds (usually in engineering contexts).

    Quantifiers are a kind of determiner and occur in many constructions with other determiners, like articles: e.g., two dozen or more than a score. Scientific non-numerical quantities are represented as SI units.

    Given the age of the universe and the composition of available matter, there is simply not enough time to grow black holes larger than this mass. The limit is only 5 × 10 10 M ☉ for black holes with typical properties, but can reach 2.7 × 10 11 M ☉ at maximal prograde spin (a = 1). [a] TON 618: 4.07 × 10 10 [22] Estimated from quasar C ...

  8. Metric prefix - Wikipedia

    en.wikipedia.org/wiki/Metric_prefix

    However, megagram, gigagram, and larger are rarely used; tonnes (and kilotonnes, megatonnes, etc.) or scientific notation are used instead. The megagram does not share the risk of confusion that the tonne has with other units with the name "ton". The kilogram is the only coherent unit of the International System of Units that includes a metric ...

  9. Mass versus weight - Wikipedia

    en.wikipedia.org/wiki/Mass_versus_weight

    Nevertheless, one object will always weigh more than another with less mass if both are subject to the same gravity (i.e. the same gravitational field strength). In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), but weight is the force exerted on an object's matter by gravity. [1]
