I am using the Canvas theme from WooThemes, and running the WooCommerce plugin for my e-commerce website. My products are measured in Square Feet, and the order quantities range widely with random numbers of sq. ft. ordered.
The units of measure available to me in the WooCommerce cart do not include sq. ft., and the quantity selector only contains pre-selected quantities that range from 1 through 9.
How can I change the unit of measure to show sq. ft. and the quantity amount in the cart / check-out to be input manually as random numbers? For example: 1253 sq. ft.
