Lakhs to Moles (lakh to mol)
1 lakh equals 1.660539067×10⁻¹⁹ moles (rounded).
How to convert lakhs to moles
To convert lakhs to moles, multiply the number of lakhs by 1.660539067×10⁻¹⁹. The factor is rounded to 10 significant digits. To go the other way, multiply moles by 6.02214076×10¹⁸.
moles = lakhs × 1.660539067×10⁻¹⁹
Example: 10 lakhs = 1.660539067×10⁻¹⁸ moles.
Large-number names differ around the world: this site uses the short scale (billion = 10⁹) by default, and lists the long-scale billion separately.
About these units
Lakh (lakh)
One hundred thousand (10⁵). The standard unit in the Indian numbering system, written 1,00,000.
Gambling stakes may have named the lakh. The Sanskrit word lakṣa originally meant a mark, a target or a stake in gambling, and in the Classical Sanskrit of the Gupta era it became the numeral for 100,000. English borrowed it from South Asia, and other languages did too: in Malay and Indonesian, laksa means 10,000 instead. The Indian numbering system gives a name to nearly every second power of ten, which is why a hundred thousand gets its own word rather than being called ten myriads or a hundred thousands.
A lakh is 100,000, written 1,00,000 under Indian digit grouping: the first three digits from the right form one group and every later group has two digits. It is the everyday system in India, Pakistan and Bangladesh, where it is preferred over the international one. Rupee amounts are stated in lakhs, so 150,000 rupees is 1.5 lakh. Indian English also uses lakhs of as a loose phrase for very many, and formal publications usually give foreign currencies in the international system and rupees in lakhs and crores.
1 lakh = 100,000 pieces (exactly).

Mole (mol)
Exactly 6.02214076×10²³ entities (the Avogadro number). The SI unit for amount of substance in chemistry.
The mole counts particles the way a dozen counts eggs, only on a vastly larger scale: exactly 6.02214076 × 10²³ elementary entities, which may be atoms, molecules, ions, electrons, or other specified particles. The mole became the seventh SI base unit in 1971, and the term itself dates from around 1900, shortened from the German Molekül. In 1909 Jean Perrin named the number in honor of Amedeo Avogadro.
Until 2019 a mole was the number of atoms in 0.012 kilogram of carbon-12, so the count depended on the kilogram. Effective May 20, 2019, the SI fixed the number itself, and the mole no longer rests on a physical sample. As a result the molar mass of carbon-12 is no longer known exactly. The chosen number kept it at 0.012 kilogram per mole, with a relative uncertainty of 4.5 × 10⁻¹⁰, at the moment of adoption. For scale, about 18 grams of water holds roughly this many molecules.
1 mole = 6.02214076×10²³ pieces (exactly).
