A Ballooning Megabyte Budget

Everyone knows how long a minute is. And your cellphone carrier keeps close tabs on how many you have used this month. Now, in the smartphone era, more people are being forced to think about how many megabytes of data they are using.

But what, exactly, is a megabyte?

If a sampling of pedestrians on the streets of Brooklyn is any guide, most people have only a vague idea. One said a megabyte was “the amount of something we have to use the Internet,” adding, “We should have three or four.”

Miranda Popkey, 24, was closer: “It’s a measure of how much information you store. If there are too many of them, I can’t send my e-mail attachment.”

A megabyte is, in this context, 1,000 kilobytes — or about the size of a photo taken with a decent digital camera, or roughly one minute of a song, or a decent stack of e-mail.

Therein lies the problem: Counting things like minutes and text messages is fairly easy, but there is no intuitive or natural way to gauge data use.
