m, M, k, K

Explanation:
m = million
M = Mega (as in Mbyte)
K = thousand (following number 5K
k = kilo

We have had several letters along similar lines. The overall response is supported by members of The Computer Bulletin advisory panel, who were not consulted before the publication of Michael Bangham's letter and the footnote. This has brought a decision to use the standard of a lower case k for kilo and capital M, G, T and so on for mega, giga, tera and so on, when these are used in truncated form, such as Mbyte, Gbyte. Lower case letters are used when the words are spelt out in full (megabyte and so on). A lower case m will be used as shorthand for a million, as in £10m. All these abbreviations are confirmed by the Oxford Dictionary for Scientific Writers and Editors.
