The key aspects of the ultimate use of the metric system by all branches of surveying and mapping are identified. The applications of the International System of Units (SI) to survey measurements are described. These are the meter (and millimeter) for lengths, heights, and depths; the square meter and hectare for areas; degree Celsius for temperature; newton for tension; and kilopascals for pressure. It is concluded that metric conversion for the surveying and mapping professions will not be difficult. The primary concern will be the acceptance by the users of the services and products of these professions.
