    Convert Decimal 42 to Hex

    (42)10 = (?)16. Decimal 42 in hex conversion provides the detailed information on what is the hexadecimal equivalent of (42)10 and the step-by-step work for how to convert the decimal 42 to its equivalent hex (base-16) number manually.

    (42)10 in hex is equivalent to:
    4210 = 2A16

    Hence,
    (2A)16 is the hex equivalent of (42)10

    where,
    4210 is the given decimal number,
    10 in 4210 represents the base-10 or decimal number system,
    2A16 is the hex equivalent of the decimal 42,
    16 in 2A16 represents the base-16 or hexadecimal number system.

    Important Notes: (42)10 in Hex
    The below are some of the important notes to be remembered while converting the (base-10) decimal number 42 into a (base-16) hexadecimal equivalent.

    1. The initial or first remainder while performing 42 MOD-16 operation is a Least Significant Bit (LSB).
    2. The last remainder while performing 42 MOD-16 operation is a Most Significant Bit (MSB).
    3. Find the equivalent hex number for each remainders of 42 MOD-16 operation before arranging the numbers from MSB to LSB to find the hex equivalent.
    4. The remainders of 42 MOD-16 operation in hex equivalents should be written from MSB to LSB to form the hex equivalent for the given decimal number (42)10.

    For decimal values other than 42, use this below tool:

    How-to: What is (42)10 in hex?

    The below step-by-step solution shows how to convert (42)10 to its equivalent hexadecimal number. Represent each remainders of 42 MOD-16 operation in hex equivalents and arranging them from MSB to LSB produces the hex equivalent of 42.



    Solved Example:
    What is the hex equivalent of 42?

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

    Input values:
    Decimal Number = (42)10

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

    step 2 Perform successive MOD-16 operation for decimal 42 until the quotient becomes 0, and mark the initial remainder as LSB and the final remainder as MSB as like the below:

    Successive MOD-16 Operation for 42
    42 MOD-16     42 / 16 = 2  Remainder is 10 → LSB
    2 MOD-16     2 / 16 = 0  Remainder is 2 → MSB

    step 3 Use the below table to find the equivalent hex representation for each remainders of successive 42 MOD-16 operation:
    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

    Decimal 10 in hex is A → LSB
    Decimal 2 in hex is 2 → MSB


    step 4 Write the remainders of 42 MOD-16 operation in hex equivalents from MSB to LSB produces the equivalent hex (base-16) number for decimal (base-10) 42:
    = 2A
    (42)10 = (2A)16

    Therefore,
    the hex equivalent of 42 is (2A)16.
