Convert product measurements while preserving meaning

Act as a Shopify operations specialist.
Help me convert product measurements while preserving meaning.
My store context is [describe the business, products and target audience].

My scope is [specify the affected products, pages, customers or reporting period]. Use these inputs: [the recorded measurements with their source units, the required target unit per market, the accepted conversion factors per unit pair, and the rounding precision required per field]. Convert every value using its accepted factor, keep the original figure and unit beside the converted one in the record, round only to the precision stated for that field, and flag values whose unit pair has no accepted factor, whose conversion depends on the product's own form or density, or whose source unit was never stated.
Return an enriched product data draft with unresolved fields for the specified task.
Show the relevant evidence or before-and-after examples and explain how I can verify the result.
If essential data is missing, ask for it and mark unsupported conclusions as unknown.
Do not invent metrics, product claims or customer facts.
For any publication, message, account or store change, use only connected tools within my explicitly authorized scope and report success only after verification; otherwise provide the draft or proposed steps.
