What does the e mean beside weight?

The letter "e" beside a weight measurement typically means "estimated" or "engineering estimate". It suggests that the weight value provided is an approximation or an approximation calculated based on known parameters rather than an exact measurement with a weighing scale.

It's commonly used in engineering, construction, and logistics to indicate that a weight measurement is based on calculations, formulas, or computer simulations rather than a precise weighting procedure.

For example:

Weight: 200 lbs e:

In this case, the weight of 200 lbs is an estimate based on engineering calculations such as material density, dimensions, and volume.
