Convert 248 from decimal to binary

(base 2) notation:

Power Test

Raise our base of 2 to a power

Start at 0 and increasing by 1 until it is >= 248

20 = 1

21 = 2

22 = 4

23 = 8

24 = 16

25 = 32

26 = 64

27 = 128

28 = 256 <--- Stop: This is greater than 248

Since 256 is greater than 248, we use 1 power less as our starting point which equals 7

Build binary notation

Work backwards from a power of 7

We start with a total sum of 0:

27 = 128

The highest coefficient less than 1 we can multiply this by to stay under 248 is 1

Multiplying this coefficient by our original value, we get: 1 * 128 = 128

Add our new value to our running total, we get:
0 + 128 = 128

This is <= 248, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 128

Our binary notation is now equal to 1

26 = 64

The highest coefficient less than 1 we can multiply this by to stay under 248 is 1

Multiplying this coefficient by our original value, we get: 1 * 64 = 64

Add our new value to our running total, we get:
128 + 64 = 192

This is <= 248, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 192

Our binary notation is now equal to 11

25 = 32

The highest coefficient less than 1 we can multiply this by to stay under 248 is 1

Multiplying this coefficient by our original value, we get: 1 * 32 = 32

Add our new value to our running total, we get:
192 + 32 = 224

This is <= 248, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 224

Our binary notation is now equal to 111

24 = 16

The highest coefficient less than 1 we can multiply this by to stay under 248 is 1

Multiplying this coefficient by our original value, we get: 1 * 16 = 16

Add our new value to our running total, we get:
224 + 16 = 240

This is <= 248, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 240

Our binary notation is now equal to 1111

23 = 8

The highest coefficient less than 1 we can multiply this by to stay under 248 is 1

Multiplying this coefficient by our original value, we get: 1 * 8 = 8

Add our new value to our running total, we get:
240 + 8 = 248

This = 248, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 248

Our binary notation is now equal to 11111

22 = 4

The highest coefficient less than 1 we can multiply this by to stay under 248 is 1

Multiplying this coefficient by our original value, we get: 1 * 4 = 4

Add our new value to our running total, we get:
248 + 4 = 252

This is > 248, so we assign a 0 for this digit.

Our total sum remains the same at 248

Our binary notation is now equal to 111110

21 = 2

The highest coefficient less than 1 we can multiply this by to stay under 248 is 1

Multiplying this coefficient by our original value, we get: 1 * 2 = 2

Add our new value to our running total, we get:
248 + 2 = 250

This is > 248, so we assign a 0 for this digit.

Our total sum remains the same at 248

Our binary notation is now equal to 1111100

20 = 1

The highest coefficient less than 1 we can multiply this by to stay under 248 is 1

Multiplying this coefficient by our original value, we get: 1 * 1 = 1

Add our new value to our running total, we get:
248 + 1 = 249

This is > 248, so we assign a 0 for this digit.

Our total sum remains the same at 248

Our binary notation is now equal to 11111000

Final Answer

We are done. 248 converted from decimal to binary notation equals 111110002.


What is the Answer?

We are done. 248 converted from decimal to binary notation equals 111110002.
