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