EPDs often report both metric and imperial values; you should check the units to ensure you use the correct values.

• A. Convert all to metric
• B. Check the units to ensure correct values
• C. Ignore units
• D. Assume imperial is standard

Answer: (B)

EPDs may present values in both metric and imperial, so the crucial step is to verify the units before using any number. Each value is tied to a specific unit, and the same quantity can look different when expressed in different systems. By checking the units first, you know which value to apply and whether a conversion is needed, ensuring accuracy in calculations and comparisons. Converting everything to metric without first confirming the units can cause errors, and assuming imperial is standard or ignoring units would lead to incorrect results.
