Convert 143 from decimal to hexadecimal
(base 16) notation:
Power Test
Raise our base of 16 to a power
Start at 0 and increasing by 1 until it is >= 143
160 = 1
161 = 16
162 = 256 <--- Stop: This is greater than 143
Since 256 is greater than 143, we use 1 power less as our starting point which equals 1
Build hexadecimal notation
Work backwards from a power of 1
We start with a total sum of 0:
161 = 16
The highest coefficient less than 15 we can multiply this by to stay under 143 is 8
Multiplying this coefficient by our original value, we get: 8 * 16 = 128
Add our new value to our running total, we get:
0 + 128 = 128
This is <= 143, so we assign our outside coefficient of 8 for this digit.
Our new sum becomes 128
Our hexadecimal notation is now equal to 8
160 = 1
The highest coefficient less than 15 we can multiply this by to stay under 143 is 15
Multiplying this coefficient by our original value, we get: 15 * 1 = 15
Add our new value to our running total, we get:
128 + 15 = 143
Hexadecimal (10 - 15) are represented by an (A-F) where 15 translates to the letter F
This = 143, so we assign our outside coefficient of F for this digit.
Our new sum becomes 143
Our hexadecimal notation is now equal to 8F
