Metric Conversion

Since 1960, most countries in the world, including New Zealand, have converted from varying methods of measurement to the Système International d’Unités (SI). The traditional English system for money and measurement denominations has been retained in this book, in keeping with the sources used and with the other volumes of the Official History of New Zealand in the Second World War series.

The following information is supplied for conversion purposes:
