As I said, I've forgotten the formulation totally. But you can see the result of this 计量检定员.

and your question was - squirrel (234 bytes) 2008-01-11, 09:15:34 (197259)
- let's start with some simple ones - Enlighten (344 bytes) 2008-01-11, 09:49:10 (197271)
  - 2.7km/s = 2.7m/ms, is this correct? (无内容) - squirrel (0 bytes) 2008-01-11, 10:41:31 (197290)
    - i think so. if you think of it as 8x10^3 m / 3x10^3 ms. (无内容) - Enlighten (0 bytes) 2008-01-11, 10:49:51 (197295)
      - 2.7km/s = 2.7m/ms = 0.0027km/ms - squirrel (143 bytes) 2008-01-11, 10:56:33 (197299)
        
        i'm not sure. but i think you can't say - Enlighten (217 bytes) 2008-01-11, 11:04:17 (197302)
        
        ok, i think the problem arises when you use m and ms. - Enlighten (184 bytes) 2008-01-11, 11:07:13 (197303)
        
        You gave "3.0000000s", not 3s. - squirrel (79 bytes) 2008-01-11, 11:09:48 (197307)
