Engineering Unit Conversion Workbook

About this resource

This workbook keeps the unit conversions used in day-to-day mechanical and process engineering in one place. It covers length, mass, force, pressure, torque, power, energy, velocity and volumetric flow, with a visible factor table showing every unit and its SI value.

Choose the quantity, enter a value, and select the from and to units. The result is calculated from the factor table, so the same table can be checked and extended. Temperature is handled separately with explicit offsets because it is an affine scale, not a simple ratio.

A complete factor table lists every supported unit, its SI factor and its quantity type. The instructions explain how to add a new unit safely and how to check a conversion by hand.

Use it for design notes, supplier data, test reports and quick checks. For legal, contractual or safety-critical values, confirm the conversion against the applicable standard or a validated calculation.

Prerequisites and technical context

Intended audience

working-engineer, engineering-team, early-career-engineer, student, educator-trainer

Prerequisites

• The source value and its current unit
• The unit required for the output

Unit systems

• SI base and derived units
• Common imperial and US customary units

Assumptions

• Conversion factors are exact SI definitions where they exist
• Temperature uses explicit offsets, not a ratio
• Units are converted directly without rounding between steps
• The factor table is the single source for every conversion

Technical notes

• Result = value × from-unit SI factor ÷ to-unit SI factor.
• Temperature: °F = °C × 9/5 + 32; K = °C + 273.15.
• Add a new unit by adding its name, SI factor and quantity type to the factor table, then extend the relevant drop-down list.
• The displayed result uses six decimal places; the underlying value is not rounded.

References

• No external standards or references listed.

Scope and limitations

Included

• Length, mass, force, pressure, torque, power, energy, velocity and volumetric flow
• Temperature conversion with explicit offsets
• Full factor table with unit, SI factor and quantity type
• Drop-down unit selection for each quantity
• Instructions and licence sheets

Not included

• Currency, financial or non-engineering conversions
• Uncertainty propagation and significant-figure rules
• Material-specific or temperature-dependent property data
• Validation of the value being converted

Limitations

• The result is only as reliable as the source value and the selected units.
• The factor table covers common engineering units, not every regional or obsolete unit.
• For contractual or safety-critical values, confirm the conversion against the applicable standard.

Author and review information

Author / publisher: Engineering Resources

Review status: Author checked

Factors are taken from exact SI definitions and standard conversion relationships. The default sheet includes a worked example for each quantity type and a separate temperature section.

Review scope: Formulas, worked defaults and stated assumptions were checked against the classical equations named on each sheet. No independent third-party review was commissioned.
