If a product feature has a dimension of 1.8 + .03, what is the upper tolerance dimension?

The upper tolerance dimension is calculated by adding the nominal value of the dimension to the specified tolerance. In this case, the nominal dimension is 1.8, and the tolerance is +0.03.

To find the upper tolerance dimension, you would perform the following calculation:

1. Start with the nominal dimension: 1.8

2. Add the upper tolerance: 0.03

So, 1.8 + 0.03 equals 1.83. This result represents the maximum allowable size for the product feature while still conforming to specifications. Therefore, the upper tolerance dimension is 1.83, confirming that this is the correct answer.
