I'm transcribing part of a biology book and I'm not sure how to braille the symbol for micrometer (μm). The sentence reads:
"Mitochondria are sausage-shaped organelles 1-3 μm long."
I know the μ is Greek for mu (braille dots 1, 3, 4). I don't think it requires a letter indicator because it's not freestanding. What do you suggest?
