Sure outside of computing in other science it has a meaning but in binary computing traditionally prefix + byte implied binary number quantities.

Many things acquire domain specific nuanced meaning ..

Even in computing the binary definition is only used with memory sizes. E.g. storage, network speeds, clock rates use the standard definition.

And yet in computing, a 1kHz clock is still 1000 cycles per second, and 1 MFLOP is still 1,000,000 floating-point operations per second.
