Fractional Notation Depending on the industry, dimensions appear in either decimal or fractional form. The way you format these measurements communicates professionalism, precision, and competence to your client, builder, or customer.
Proper Formatting and Placement of Dimension Text on Technical Drawings
Conversely, scientific, architectural, and many international technical drawings prefer decimal notation (e. Clearly stating the tolerance—either in the dimension itself or in a separate note—manages expectations regarding manufacturing variability.
For example, a standard shipping box is written as 12" x 8" x 4", where 12 inches is the length, 8 inches is the width, and 4 inches is the height. A number without a unit is meaningless in a technical context.

Furthermore, precision matters; writing 100 mm implies a different tolerance than 100. Clearly stating the tolerance—either in the dimension itself or in a separate note—manages expectations regarding manufacturing variability.
