    These were hour glass shaped measure used for Milk, Ghee, Oils. The bottom was round like an inverted dome, the top was like flared rim. This shape helped in pouring the liquids. 4 Chhataank = 1 Pav 4 Pav = 1 Seer 40 Seer = 1 Maund Length Measure. Measure of length is Gaz. To interpret Gaz, depends on what one is measuring and where they are.

  3. Mass–energy equivalence - Wikipedia

    en.wikipedia.org/wiki/Mass–energy_equivalence

    Mass near the M87* black hole is converted into a very energetic astrophysical jet, stretching five thousand light years.. In physics, mass–energy equivalence is the relationship between mass and energy in a system's rest frame, where the two quantities differ only by a multiplicative constant and the units of measurement.

  4. Density - Wikipedia

    en.wikipedia.org/wiki/Density

    As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m 3) and the cgs unit of gram per cubic centimetre (g/cm 3) are probably the most commonly used units for density. One g/cm 3 is equal to 1000 kg/m 3. One cubic ...

  5. Blood sugar level - Wikipedia

    en.wikipedia.org/wiki/Blood_sugar_level

    Unit conversion formula from mmol/L to mg/dL [5] m g / d L = m m o l / L × m o l e c u l a r w e i g h t ÷ 10 {\displaystyle mg/dL=mmol/L\times molecular\ weight\div 10} Since the molecular mass of glucose C 6 H 12 O 6 is 180.156 g/mol, the factor between the two units is about 18, so 1 mmol/L of glucose is equivalent to 18 mg/dL.

  6. Italian units of measurement - Wikipedia

    en.wikipedia.org/wiki/Italian_units_of_measurement

    The units to measure length, volume, mass, etc., could differ widely between countries or between towns in a country (e.g. Rome and Ancona), but usually not between a country and its capital. The Kingdom of Sardinia included the island of Sardinia and the continental areas of Piedmont (with the capital Turin) and Liguria (with Genoa).

    It is estimated that a 70 kg (154 lb) person might drink 4.8 litres (1.3 US gal) of heavy water without serious consequences. [23] Small doses of heavy water (a few grams in humans, containing an amount of deuterium comparable to that normally present in the body) are routinely used as harmless metabolic tracers in humans and animals.

    The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale".

    It is the angle of the equilateral triangle or is ⁠ 1 / 6 ⁠ turn. 1 Babylonian unit = 60° = π /3 rad ≈ 1.047197551 rad. hexacontade: 60: 6° The hexacontade is a unit used by Eratosthenes. It equals 6°, so a whole turn was divided into 60 hexacontades. pechus: 144 to 180: 2° to 2°30′ The pechus was a Babylonian unit equal to about ...
