What are conversion factors used for?

• A. Values used to convert between measurement units
• B. Standards published by ASTM
• C. Documents cited for standards
• D. Innovations that pass safety checks

Answer: (B)

Conversion factors are values used to convert between measurement units. In NFPA 13R design and related calculations, you often work with different unit systems—gallons per minute versus liters per minute, feet versus meters, psi versus kPa. Using conversion factors lets you translate all quantities into a consistent set of units, ensuring that flow, pressure, hydrant, and pipe-sizing calculations are accurate and comparable. They aren’t standards or documents; they’re numerical multipliers that bridge different measurement systems. Standards published by ASTM or documents cited for standards aren’t conversion factors themselves, and they don’t perform unit conversions.
