"1.32 MB" Is that pronounced, "one-point-three-two" megabytes, or "one-point-thirty-two" megabytes?

Usually one point three two

I grew up with science classes telling us always state the digits individually. One point three two.

Math class taught me to be precise I should always say "1 and 32 hundredths Megabytes"
- I don't think that's any more precise, just more verbose (read: inefficient).

One point three two. To me, thirty two is an integer.

The only way you could use 'thirty two' correctly for that number would be 'one and thirty two hundredths' which would be pretty unusual.
Agree. For things like semantic versioning, in which "1.20.1" and "1.2.1" are two different things, you want to pronounce them "one point twenty point one" and "one point two point one", respectively. But that is a bit of an outlier. File size should be pronounced "normally", because "1.20" and "1.2" are the same value.
- I disagree. I would personally find one point two zero point one to be more natural and easier to understand.

The first one is correct as others have said, but the second one is not ambiguous enough to confuse anyone nor weird enough for anyone to bat an eye at, you're fine with either.

I'd say the second one is more correct, it sounds so weird pronouncing the digits singularly
- I’d say the second one is more correct
  In this case, it's not about what sounds good or personal opinion, there is a standard name for that number for a reason. If I go around calling 100 "one oh oh" or "tenty ten", it's clear what number I mean but I can't honestly call it more correct, because there's a standard English name for it.
  To demonstrate a part of why it's clearer that way, put these numbers in ascending numerical order: (e.g. 1, 2, 3, ... )
  one point three
  one point twenty-nine
  one point thirty
  one point thirty-one
  one point three-thousand-and-fifty-two
  Hopefully this clarifies that we're not actually dealing with a "thirty-two" when we're talking about 1.32 (edit: that said, when we're talking about version numbers, e.g. Linux kernel 4.20, which is greater than Linux kernel 4.9, then we'd say "four point twenty")

I mostly heard it one point thirty two? Grew up in Sweden, living in France. If someone says one point three two I'd assume they're Americans.

I might be totally wrong, just stating what I have heard

No that's interesting, I was wondering if there was a cultural divide.
Thirty two sounds so alien to me, but I heard it in a Nerdstalgic video and wondered if it was an American thing
- Definitely, in frech itd be un point trente-deux mégaoctets or 1.32mo
  edit: forgot not everyone speaks french, the french version is one point thirty-two
I had the same experience (also European), but didn't know the Americans changed it specifically for bytes
- We don't. That's just the normal way most people pronounce numbers with a decimal point. The big exception is prices: $1.32 is often pronounced "one thirty two".

One point four four

I have heard people drop the "point" and say "One Fourty-four".
- Tree fiddy!
- criminal!
  “One fourty-four Em Bee floppy”

The first one

One point three two, or one three two if it's obvious from context where the decimal point is. That's how you're meant to pronounce digits after the decimal point in general.

The former.

"about a meg" because it's almost unthinkable anyone cares about 3 tenths of a meg much less 2 hundredths.

"about a meg" because it's almost unthinkable anyone cares about 3 tenths of a meg much less 2 hundredths.
Tell me you never used floppy discs as a storage medium without telling me.
I'd round up to one and a half. Also remove "bytes" and "bites". 1.32 MB is "one and a half megs" or even "a meg and a half"

Canada (Ontario) here. Was taught explicitly to say "point three two"

Neither.

It's pronounced: "one and thirty-two hundreths of a megabyte". Properly.

But idgaf how you pronounce it as long as I understand exactly what you're saying. Personally, "one point three two".

First question, and it’s important: Are you Doc Brown?

I'd say one point thirty-two. As others noted, much depends on geography.

Personally, I say the "actual" number up to 3 or 4 decimal places, with a lot of the reason depending on the specific context. If I had to asses, I'd say I say the "whole" number in over 50% of cases for 3 digits, and in about 10% for 4 digits. Anything over 4 decimal places and I fall back to individual digits.

Its pronounced 'About four thirds megabytes.'

Depending on the necessary precision it could be "a meg and change" 😁

Only time I can think of where the 32 of 1.32 could be said as thirty-two would be as a software version number

One point three two emm bee 😁

Either way

Either way but usually the former

Is that either way or either way?
- The second you heathen.

Both depending on what I feel like saying.

Not quite one and a half megabytes. Otherwise, one point three two.

I’m gonna have to side against Doc Brown on this one, as much as it pains me to say.

just one-three-two, the point is implied

I was told a long time ago by a teacher that "there are no whole numbers after the comma". That is to say, one should say one-point-three-two, but not a lot of people I've met since care either way.

One point three two megs

One point thirty two

Usually the first unless you’re on radio then it’s preferred to read out numbers as each digit. “One decimal three two”
