[GIS] 1ft contour shapefile displaying in meters

contourelevationqgisunits

I generated a shapefile that has 1ft contours. It works great when imported to QGIS except the elevation labels are displayed in meters instead of feet. I've found two places to select feet as the unit of measurement, but they are for distance and area, not elevation.

How do I get my 1 ft contour lines to display in feet instead of meters?

That is, I want: 18ft, 19ft, 20ft instead of 5.486m, 5.791m, 6.096m.

That will be in the attribute data of the contours. You'll probably have a column labelled 'ELEV' or something for the metre measurement. Just create a new column with the field calculator using:

'ELEV' / 0.3048

That should could a new column with all metre converted to feet. Then use that column to label the contours.

Alternatively for something not as permanent you can use the same equation as above in the label properties
