    What is 1E9 hex in decimal?

    Answer

    Hexadecimal number 1E9 (0x1E9) in decimal is
    489

    Read as an unsigned hex number — A = 10 … F = 15, case does not matter, 0x is only a prefix.

    In scientific notation 1e9 would mean 1 × 10⁹ — a different number.

    Digit × place value, then add

    1×256 + 14×16 + 9×1 = 256 + 224 + 9 = 489
