Can I ask why, though? I’m also an engineer and I just never spell it out, if I can avoid it (so far, luckily, haven’t had push back since I’m on delivery and not proposals or anything like that.)
To me, it’s just more annoying to read it as words, and no matter what you do, mistakes can still happen, including when it’s spelled out.
Just my 2 cents.

I’ll write out a count without a digit if it’s immediately next to a value. Like without other qualifiers: “three 500 kVA transformers”, versus “3 500 kVA transformers” (horrible), or even “three [3] 500 kVA transformers” (acceptable, but perhaps cluttered)
(Also note the space between value and unit—technically required but I’m not consistent about it)
