It originated from China and later spread to Japan, the Korean Peninsula, Vietnam and other places. [1] One sheng equals 10 ge or 1/10 dou, though its specific capacity has varied by times and regions. Nowadays, 1 sheng is 1 liter in China, [2] [3] 1.8039 liters in Japan [4] and 1.8 liters in Korea. [5] Sheng is a traditional measure for cereal ...
The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes. For example, a gigagram ( Gg ) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .
However, 1 and 15 are not within an order of magnitude, since their ratio is 15/1 = 15 > 10. The reciprocal ratio, 1/15, is less than 0.1, so the same result is obtained. Differences in order of magnitude can be measured on a base-10 logarithmic scale in " decades " (i.e., factors of ten). [ 2 ]
The Bubble Nebula (NGC 7635) at left with about 520 cubic light years (4.4 × 10 50 m 3) dwarfs the Dumbbell Nebula's 12 cubic light years (1 × 10 49 m 3) (very approximate figures) The globular cluster Messier 5 at upper left with about 2 million cubic light years (1.7 × 10 54 m 3) dwarfs the much smaller Bubble Nebula at lower right.
Here, the base units are the quad, equal to 10 7 m (approximately a quadrant of the Earth's circumference), the eleventhgram, equal to 10 −11 g, and the second. These were chosen so that the corresponding electrical units of potential difference, current and resistance had a convenient magnitude. [36]: 268 [37]: 17
The litre (Commonwealth spelling) or liter (American spelling) (SI symbols L and l, [1] other symbol used: ℓ) is a metric unit of volume. It is equal to 1 cubic decimetre (dm 3 ), 1000 cubic centimetres (cm 3 ) or 0.001 cubic metres (m 3 ).

When units occur in exponentiation, such as in square and cubic forms, any multiples-prefix is considered part of the unit, and thus included in the exponentiation.. 1 Mm 2 means one square megametre or the size of a square of 1 000 000 m by 1 000 000 m or 10 12 m 2, and not 1 000 000 square metres (10 6 m 2).
