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).

Quadrillion (quad)
10¹⁵ in the short scale.
Quadrillion is 10¹⁵, a thousand trillion, on the short scale, and it is a number most people meet only through energy statistics. The U.S. Energy Information Administration defines a quad as a quadrillion British thermal units and notes that national energy use typically reaches quadrillions of Btu. Its examples include 35.43 quads from petroleum, 33.61 from natural gas, and 8.17 from coal.
The name uses the Latin quadri-, four. It appears among the terms in Nicolas Chuquet's unpublished manuscript of 1484, alongside byllion and tryllion. On the long scale the same 10¹⁵ is called a billiard, and a quadrillion means 10²⁴. The SI prefix for 10¹⁵ is peta-. A quadrillion seconds is about 31.7 million years.
1 quadrillion = 1×10¹⁵ pieces (exactly).
