Convert engineering units with context
Convert length, pressure, temperature, and flow values in seconds with transparent formulas, assumptions, and bilingual English–Spanish explanations.
Start with a quick 1 bar → 100 kPa example or enter your own value.

04 / A practical conversion reference
A practical conversion reference
Kernspan keeps common engineering conversions close at hand for early design checks, field notes, and specification reviews. The calculator covers the unit families people reach for most often: length, pressure, temperature, and flow.
Every result includes the source and destination units, a readable formula note, and assumptions in plain language. That context makes it easier to sanity-check a number before it moves into a drawing, schedule, or equipment decision.
Make the conversion, then keep the context with the number as you review your work.
- 01Select the engineering quantity you want to convert.
- 02Enter a finite value and choose the source and destination units.
- 03Review the result, formula, and assumptions before applying it to your work.
05 / Formulas you can audit

The converter keeps the math visible so you can check how a value moves through its reference unit.
Base value = input × source factor; result = base value ÷ destination factor. Length, pressure, and flow use a reference unit: m, Pa, and m³/s.
C = (F − 32) × 5/9; K = C + 273.15. Reverse equations are applied when converting back to Fahrenheit or Celsius.
06 / Preliminary-use note
Preliminary-use note
This is a preliminary conversion aid, not a final design or safety authority. Verify inputs, standards, material data, and project-specific conditions with the responsible engineer before issuing work or making a safety decision.
