Page role

Use this page for a defined task before moving to the next project record.

Audience: Users running unit conversion tools for a known project condition.
Job: Move from input evidence to a calculator result, then into a standard hub, worksheet, reference table, or authority review.
Evidence: Pressure, Flow, Length, Area, Pipe schedule
Output: Converted value, Internal diameter, Reference-ready value
Next: Use the workflow table before opening individual tools; keep reviewed outputs with the project workpaper.

Unit Conversion Tools workflow

Use this category page as a workflow control surface: confirm entry conditions, run the tools, review quality gates, and keep the records.

Phase	Workflow step	Inputs	Outputs	Quality gate
Phase 1 Conversion	Normalize field values into the units required by the calculator.	Pressure, Flow, Length	Converted value, Internal diameter, Reference-ready value	Inputs have been checked against drawings, device listings, field test records, or project criteria.
Phase 2 Conversion	Check pipe diameter assumptions before using friction and velocity formulas.	Flow, Length, Area	Internal diameter, Reference-ready value	Outputs including Converted value, Internal diameter, Reference-ready value have been reviewed before project use.
Phase 3 Conversion	Keep converted values visible next to the tool that consumes them.	Length, Area, Pipe schedule	Reference-ready value	Warnings, failed screens, or narrow margins are documented before moving to the next workflow.

Phase 1

Conversion

Normalize field values into the units required by the calculator.

Pressure, Flow, Length

Converted value, Internal diameter, Reference-ready value

Inputs have been checked against drawings, device listings, field test records, or project criteria.

Phase 2

Conversion

Check pipe diameter assumptions before using friction and velocity formulas.

Flow, Length, Area

Internal diameter, Reference-ready value

Outputs including Converted value, Internal diameter, Reference-ready value have been reviewed before project use.

Phase 3

Conversion

Keep converted values visible next to the tool that consumes them.

Length, Area, Pipe schedule

Reference-ready value

Warnings, failed screens, or narrow margins are documented before moving to the next workflow.

Entry conditions

1Use this workflow when the task belongs to unit conversion tools and the controlling project condition is known.
2Collect Pressure, Flow, Length, Area before opening individual calculators.
3Confirm the values are project-specific, field-measured, manufacturer-listed, or selected from linked reference tables.

Records to keep

1Unit Conversion Tools input source checklist.
2Reviewed output set: Converted value, Internal diameter, Reference-ready value.
3Linked reference values used for the calculation basis.
4Next-step review note for final calculation package, field review, or submittal check.

Choose the conversion by the downstream value

Use this matrix when a field, drawing, or equipment value needs normalized units before another fire protection calculator consumes it.

How to use this category

1Confirm the category matches the actual project task before choosing a calculator.
2Collect Pressure, Flow, Length, Area from drawings, field data, listings, criteria, or linked references.
3Run the smallest calculator that answers the immediate question, then review warnings and pass states.
4Move reviewed results into a worksheet, standard hub, or authority record; separate downloadable products are optional and only belong where a real workflow product exists.
5Use these tools directly without an account; keep the workflow focused on calculations, references, worksheets, and authority records.
