# What is 10 1 10

## Dictionary

In physics, very large and very small numerical values ​​are usually written using powers of the number 10. For large numbers is 10n, with n a nonnegative integer, a 1 with n trailing zeros, for example:

100 = 1 = one
101 = 10 = ten
102 = 100 = hundred
103 = 1000 = thousand
106 = 1,000,000 = one million
109 = 1,000,000,000 = one billion
1012 = 1,000,000,000,000 = one trillion
1015 = 1,000,000,000,000,000 = one quadrillion

Very small fractions can be classified as 10-n, write with n a nonnegative integer. n also counts the zeros here:

 100 = 1 = one 10-1 = 0,1 = a tenth 10-2 = 0,01 = a hundredth 10-3 = 0,001 = a thousandth 10-6 = 0,000001 = a millionth 10-9 = 0,000000001 = a billionth 10-12 = 0,000000000001 = one trillionth 10-15 = 0,000000000000001 = a billiard part

Numbers that are not an even power of ten can be written by extracting the power of ten as a factor: This is something like this

1748 = 1,748·1000 = 1,748·103

in calculators also written 1,748E3. As an example of a small number is

0,000.4175.5 = 4,1755·0,0001 = 4,1755·10-4 = 4.1755E-4.
