One lakh fifty thousand written in figures is 1,50,000. In the Indian numbering system, a lakh is equal to 100,000, so one lakh fifty thousand is equivalent to 150,000 in the standard numbering system used in many other countries.
A duodecillion is equal to 1 followed by 39 zeros in the short scale (American) numbering system. In the long scale (British) numbering system, a duodecillion is equal to 1 followed by 72 zeros. Therefore, in the short scale system, there are 39 zeros in a duodecillion.
The beauty of metric system is that it is decimal. 0.51cm = 5.1mm
In the Indian numbering system, one lakh is equal to 100,000. Therefore, 4 lakh is equal to 400,000. There are four zeros in 400,000.

The number system we commonly used, known as the decimal system, has 10 digits (0 to 9). It is possible to use other number systems, with a different number of digits. Any numbering system based on the same principle (the principle of place-value) must use 2 or more digits.
16 The current hexadecimal system was first introduced to the computing world in 1963 by IBM.
This is an Indian numbering system equal to 10 Million. Therefore 10,000,000. (7)
