## How-to: What is (42)16 in decimal?

The below step-by-step solution shows how to convert the hexadecimal number (42)16 to decimal. To find the decimal equivalent of (42)16, replace each digit of the given hex number by the equivalent decimal number, so (42)16 becomes 4 2. Find the product of 160 and 2, 161 and 4. The sum of all individual products is the decimal equivalent of hex 42.

Solved Example:
Convert the hexadecimal number (42)16 to decimal equivalent.

step 1 Observe the input parameters, values and what to be found:

Input values:

What to be found:
What is the decimal equivalent of hexadecimal (42)16?
(42)16 = (?)10

step 2 Replace each digit of the given hex number (42)16 by the equivalent decimal number by referring the below hex and decimal number system table.

 Decimal: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Hex: 1 2 3 4 5 6 7 8 9 A B C D E F

From left to right of hex 42,
The decimal equivalent of hex 4 is 4
The decimal equivalent of hex 2 is 2

So, the (42)16 becomes 4 2

step 3 Multiply 160 and 2, 161 and 4 and find the sum of all individual products produce the actual decimal equivalent of hex (42)16.
= (4 x 161) + (2 x 160)

step 4 Resolve the powers of 16 in the above equation and simplify further:
= (4 x 16) + (2 x 1)
= 64 + 2
= 66
4216 = 6610

Hence,
the decimal equivalent of hexadecimal number (42)16 is (66)10
