Metric/Imperial Conversions


1 metre (1m) is approximately 3ft 3in (39.37in). 1 inch when converted to metric is 25.4mm.

However, when purchasing timber, you will find that there is usually a slight difference between the actual conversion measurement and the measurement used, for example, items measuring 1 inch may be sold as 25mm. Because the industry conversion is fractionally different than the actual imperial conversion, you should always measure in metric (mm, cm, m) to avoid any measurement mistakes.
