Define default input and display units for Estimating
You can use either metric or imperial units for displaying and entering sizes, lengths, weights, and prices in the Estimating module. In addition, you can select how you want to enter the length and thickness for an item.
The input and display units are saved as default units used for new estimating jobs. If necessary, you can also adjust the units used in individual jobs. For more information, see Define input and display units for an estimating job.
