A fun rule of thumb is that 1 decimal digit is roughly 3 binary digits (because 2^3 is eight, which is almost ten.)

- lorenzhs 10y agoThat's terribly far off. On the other hand, 2^10 and 10^3 are reasonably close at 1024 and 1000. That's good enough for many things. But it's also the difference between a Kibibyte and a Kilobyte, and so forth.

- paulddraper 10y ago> terribly far off lg 10 is 3.322 3 is ten percent accurate. 3.333 is one percent accurate.
- Tempest1981 10y agoI've used this many times -- handy for order-of-magnitude sanity checks. Sure, log2(10) is 3.32 or so, but it's still a quick way to remember that 32-bits is good for a billion, and 64-bits is good for a quintillion (ok, 9 quintillion unsigned)
- IshKebab 10y agoIsn't it easier to remember 10 bits ~= 1000? 32 is about 310, or 1000 1000 * 1000.
- Keyframe 10y agoNot really. BCDs are (can be) four bits per decimal digit. That's something different though.
