No it’s not true, though it is a close approximation. Another has the actual formula, but the proof that it’s incorrect is that 32°F = 0°C, while (32-30)/2 = 1.
Not good enough for chemistry, but for daily use. But I’d rather convert it with a calculator and double check the conversion if it needs to be that precise, than to calculate it by hand

That’s what I call good enough.
