SUMMARY

When converting measurement uncertainty during unit changes, the uncertainty value remains consistent regardless of the unit. For example, a length of 8.25 cm with an uncertainty of ±0.05 cm converts to 0.0825 m with an uncertainty of ±0.0005 m. This principle holds true as no additional uncertainty is introduced during the conversion process. Therefore, the conversion of uncertainty is a straightforward scaling of the original uncertainty value.

PREREQUISITES

Here's my value: length: 8.25 +/- 0.05cm
If I convert 8.25 to m how to I .. convert my uncertainty?

Your uncertainty shouldn't change with the units. .05 cm is .0005 m. After all there is no uncertainty introduced with the conversion.
