Unit Conversion Blog
Practical notes on unit conversion for scientists, engineers, and anyone who has ever stared at a spreadsheet too long.
Why Unit Conversions Still Break Engineering Calculations
Why unit mistakes persist in real workflows, plus a practical checklist to reduce errors in design notes, spreadsheets, and field work.
Read MoreMass vs Weight: The Kilogram Problem That Never Goes Away
How kilograms get misused as loads, when to apply gravity, and how to avoid mass versus force confusion in calculations and specs.
Read MorePressure Units in Practice: kPa, psi, bar, and Why Context Matters
Pressure conversion is easy. Gauge versus absolute versus differential is the part that causes mistakes. Includes quick sanity checks.
Read MoreFlow Rate Conversions Engineers Get Wrong More Than They Admit
Flow errors often come from the time base. L/s versus L/min and m3/s versus m3/h mistakes can change equipment sizing fast.
Read MoreWhy Density Units Confuse Soil and Materials Reports
The 1000x trap of g/cm3 versus kg/m3, plus how to connect density and unit weight without mixing the physics.
Read MoreTorque Units: N·m, lb-ft, and Why Fasteners Fail
Torque mistakes turn into real failures. Covers N m vs lb-ft, lb-in vs lb-ft, and practical checks before tightening critical joints.
Read MoreEnergy vs Power: Why kWh Is Not kW
Power is a rate and energy is accumulation. Learn how to avoid common kW and kWh confusion in sizing and cost estimates.
Read MoreTemperature Conversions and the Hidden Offset Problem
Temperature is not a pure scale conversion. Offsets matter, and delta T behaves differently than absolute temperature.
Read MoreLength Units in Construction: Metric Precision vs Imperial Habit
Mixed units on real projects are normal. This covers the common failure modes and how to convert without layout and tolerance surprises.
Read MoreArea Units in Land Measurement and Engineering Design
Hectares, acres, m2, and ft2 do not mix cleanly without discipline. Includes scale checks that catch common area mistakes.
Read MoreWhy Volume Units Still Trip Up Fluid Calculations
Volume is easy until it is inside a larger calculation. Covers liters, m3, gallons, and the common places assumptions break.
Read MoreHow to Sanity-Check Any Unit Conversion
A converter can be correct while the conversion is meaningless. A short set of habits that catches most real-world unit errors.
Read MoreForce Units and Load Paths: Newtons Still Matter
Why expressing loads as forces reduces ambiguity, and where kg-based shorthand causes problems in structural and civil workflows.
Read MoreSpeed vs Velocity: Units Matter More Than Direction
Speed conversions are simple. Misuse is not. Includes the 3.6 rule, squared relationships, and reference-frame pitfalls.
Read MoreCommon Unit Mistakes Found in Engineering Reports
A practical checklist of the unit mistakes that survive into deliverables, plus a simple review routine to catch them.
Read MoreWhy Unit Conversions Still Cause Engineering Errors (And How to Avoid Them)
Unit conversion mistakes are still one of the most common and preventable sources of engineering error. Here’s why they keep happening and a practical checklist to stop them.
Read MoreSI vs Imperial Units: Why Engineers Still Live in Two Worlds
Engineers routinely work across SI and imperial units, sometimes in the same project. This post explains why it still happens, where mistakes creep in, and how to work confidently across both systems.
Read MoreBest Practices for Unit Consistency in Engineering Calculations
Maintaining unit consistency is one of the simplest and most effective ways to prevent engineering errors. This post outlines practical habits that help keep calculations reliable from start to finish.
Read MoreScientific Notation and Significant Figures for Engineering Calculations
Precision is important in engineering, but more digits do not always mean more accuracy. This post explains how to use scientific notation and significant figures responsibly.
