साल के संपादन कइल जा रहल बा

'''साल''' या '''बरिस''' ओह समय के कहल जाला जवना में धरती अपने कक्षा में सुरुज के चारों ओर एक चक्कर लगा लेले।

* {{Anchor|Kiloannus|Kiloannum}} ''ka'' (किलोएनस (kiloannus) खातिर), एक सहस्राब्दि या मिलेनियम के कहल जाला आ ई एक हजार साल के बराबर होला। एकर इस्तेमाल खासतौर पर भूबिज्ञान, पैलियोओंटोलॉजी आ पुरातत्व बिज्ञान में होलोसीन के आ प्लीस्टोसीन काल के घटना खातिर होला।
* {{Anchor|Megaannus|Megaannum}} ''Ma'' (मेगाएनस (megaannus) खातिर), समय के इकाई हवे जवन दसलाख साल या एक मिलेनियम  (10<sup>6</sup>) साल के बराबर होला।<!-- It is commonly used in scientific disciplines such as geology, paleontology, and [[celestial mechanics]] to signify very long time periods into the past or future. For example, the [[dinosaur]] species ''[[Tyrannosaurus|Tyrannosaurus rex]]'' was abundant approximately ''66 Ma'' (66 million years) ago (''ago'' may not always be mentioned; if the quantity is specified while not explicitly discussing a duration, one can assume that "ago" is implied; the alternative "mya" unit includes "ago" explicitly). In astronomical applications, the year used is the Julian year of precisely 365.25 days. In geology and paleontology, the year is not so precise and varies depending on the author.-->
* {{Anchor|Gigaannus|Gigaannum}} ''Ga'' (गीगाएनस (gigaannus) खातिर), 10<sup>9</sup> साल (एक [[1000000000 (number)|बिलियन]]) या एक अरब खातिर इस्तेमाल होला। <!-- on the [[long and short scales|short scale]], one [[milliard]] on the [[long and short scales|long scale]]). It is commonly used in scientific disciplines such as [[physical cosmology|cosmology]] and geology to signify extremely long time periods in the past. For example, the formation of the Earth occurred approximately ''4.57 Ga'' (4.57 billion years) ago. -->
* {{Anchor|Teraannus|Teraannum}} ''Ta'' (टेराएनस (teraannus) खातिर),  10<sup>12</sup> साल (एक [[1000000000000 (number)|ट्रिलियन]]) या दस खरब साल खातिर इस्तेमाल होला <!-- on the short scale, one billion on the long scale). It is an extremely long unit of time, about 70 times as long as the [[age of the universe]]. It is the same order of magnitude as the expected life span of a small [[red dwarf]]. -->
* {{Anchor|Petaannus|Petaannum}} ''Pa'' (पेटाएनस (petaannus) खातिर), 10<sup>15</sup> साल (एक [[10^15|क्वाड्रिलियन]]) खातिर। <!-- on the short scale, one [[billiard (number)|billiard]] on the long scale). The half-life of the nuclide [[cadmium]]-113 is about 8 Pa.<ref>{{cite journal| author = P. Belli| display-authors = etal| title = Investigation of β decay of <sup>113</sup>Cd| journal = [[Phys. Rev.

The decay of Ta-180m had never been observed). This symbol coincides with that for the [[pascal (unit)|pascal]] without a multiplier prefix, though both are infrequently used and context will normally be sufficient to distinguish time from pressure values.-->
* {{Anchor|Exaannus|Exaannum}} ''Ea'' (ऍक्साएनस (exaannus) खातिर), 10<sup>18</sup> साल (एक [[क्विंटिलियन]]) खातिर। <!-- on the short scale, one trillion on the long scale).--> The half-life of [[tungsten]]-180 is 1.8 Ea.<ref>{{cite journal| author = F.
