Q. In the following conversion in prose, should it be written “six feet (1.80 meters)” or “six feet (1.8 meters)”?

A. This is a matter of accuracy, rather than style. Six feet is 1.8288 meters. Rounded to the nearest tenth, that’s 1.8, but rounded to the nearest hundredth, it’s 1.83. So it would be inaccurate to write 1.80. Write 1.8 or 1.83 instead.
