1. Konversi bilangan desimal

Desimal ke biner

0,84375(10) = 0,11011(2)

0,84375x2 = 1,6875 => 1(awal)

0.6875x2 = 1,375 => 1

0.375x2 = 0,75 => 0

0,75x2 = 1,5 => 1

0,5x2 = 1,0 => 1(akhir)

5,625(10)=101,101(2)

5/2=2 sisa 1(akhir)

2/2=1 sisa 0

1/2=0 sisa 1(awal)

0,625x2= 1,25 => 1(awal)

0,25x2 = 0,5 =>0

0,5x2 = 1,0 => 1 (akhir)

Desimal ke Oktal

0,293(10)=0,226(8)

0,293x8 = 2,344 => 2(awal)

0,344x8 = 2,752 => 2

0,752x8 = 6,016 => 6(akhir)

Desimal ke Hexa

205,05 (10)=DC,0CC(16)

205/16 = 12 sisa 13 =D(akhir)

12/16 = 0 sisa 12 =C (awal)

0,05 x 16 = 0,8 => 0 (awal)

0,8x 16 = 12,8 => 12=C

0,8x 16 = 12,8 =>12=C(akhir)

2. Konversi bilangan oktal

Oktal ke biner 654.37(8)=110101100,011111(2)

6=0110

5=0101

4=0100

3=0011

7=0111

Oktal ke Desimal

654,37(8)=428,484375(10)

= 6x82 +5x8

1+4x8

0+3x8

-1+7x8

-2

= 384+40+4+0,375+0,109375

= 428,484375

Oktakl ke Hexa

654,37(8)=110101100,011111(2)

= 1AC,7C(16)

Dibagi manjadi 4 dijit

0001/1010/1100,0111/1100

Jika kurang boleh di tambah 0

Maka 0001/1010/1100,0111/1100

= 1/A/C, 7/C

3. Konversi bilangan Biner

Biner ke desimal

0,1011(2)=0,6875(10)

=0x20+1x2

-1+0x2

-2+1x2

-3+1x2

-4

= 0+0,5+0+0,125+0,0625

= 0,6875

4. Konversi bilangan Hexa

Hexa ke biner

AF3,79(16)=101011110011,01111010(2) A=1010

F=1111

3=0011

7=0111

9=1001

Hexa ke Oktal AF3,7(16)=101011110011,01111010(2)

=5363,362(8)

101/011/110/011,011/110/010

Jika kurang boleh ditambah 0

5/3/6/3, 3/6/2

Hexa ke Desimal

AF3,97(8)=2803,5898(10) maka

= Ax162+Fx16

1+3x16

0+9x16

-1+7x16

-2

= 10x162+15x16

1+3x16
