names and symbols exist. (The SI units are "metre" and "litre"; the National Institute of Standards and Technology, followed by the American Chemical Society and a number of other publishers, is tenaciously retaining the traditional American spellings, "meter" and ''liter.")
Other Abbreviations
Appendix 6 provides a list of acceptable abbreviations that are now considered to be standard. Most of them are from the CBE Style Manual or from The ACS Style Guide (Dodd, 1997). Use these abbreviations when necessary. Avoid most others. Those that you use should be introduced as carefully as you would introduce royalty.
