The Micromillimetre


IN NATURE of February 23 (p. 388) there appears an interesting letter from Prof. A. W. Rücker with reference to the equivalent value of the “micromillimetre.” It is therein mentioned that the micromillimetre is commonly employed by biologists as equivalent to one-thousandth of a millimetre; but that the proper name for the thousandth of a millimetre (μ) is “micromëtre,” and not “micromillimetre.”
