https://unitly.one/blogPractical notes on units and conversions.https://unitly.one/blog/concentration-and-densityhttps://unitly.one/blog/concentration-and-densitySat, 14 Nov 2026 00:00:00 GMTTomSimilar-looking compound units can describe different measurements. Here is what a fixed-factor converter can and cannot connect.https://unitly.one/blog/gigabytes-and-gibibyteshttps://unitly.one/blog/gigabytes-and-gibibytesFri, 13 Nov 2026 00:00:00 GMTTomA drive advertises 500 GB and an application displays a number closer to 465.66. That difference can be a naming convention rather than lost data.https://unitly.one/blog/temperature-values-and-differenceshttps://unitly.one/blog/temperature-values-and-differencesWed, 11 Nov 2026 00:00:00 GMTTomCelsius, Fahrenheit and Kelvin use both scale factors and offsets. Knowing what your value means prevents a common mistake.https://unitly.one/blog/furniture-dimensions-and-clearancehttps://unitly.one/blog/furniture-dimensions-and-clearanceMon, 09 Nov 2026 00:00:00 GMTTomA desk can fit the room and still fail to pass through the doorway. Product listings often give one set of dimensions in inches, while a room plan uses centimetres.https://unitly.one/blog/package-mass-net-gross-and-tarehttps://unitly.one/blog/package-mass-net-gross-and-tareSun, 08 Nov 2026 00:00:00 GMTTomA parcel label and a supplier specification may both mention weight while referring to different amounts. One can include the box and packing; another can describe only the contents.https://unitly.one/blog/oven-temperature-celsius-fahrenheithttps://unitly.one/blog/oven-temperature-celsius-fahrenheitFri, 06 Nov 2026 00:00:00 GMTTomA recipe specifies 180 °C and the oven dial uses Fahrenheit. That is an absolute-temperature conversion, not a temperature-difference problem.https://unitly.one/blog/flooring-area-and-waste-allowanceshttps://unitly.one/blog/flooring-area-and-waste-allowancesWed, 04 Nov 2026 00:00:00 GMTTomA room plan gives 42 m² and flooring is sold by the square foot. Converting the measured area is straightforward; turning it into an order requires more decisions.https://unitly.one/blog/recipe-cups-millilitres-and-measuring-jugshttps://unitly.one/blog/recipe-cups-millilitres-and-measuring-jugsMon, 02 Nov 2026 00:00:00 GMTTomA recipe says one cup, the measuring jug shows millilitres, and a conversion chart seems to disagree with both. The word cup does not guarantee a universal volume.https://unitly.one/blog/road-speed-and-journey-estimateshttps://unitly.one/blog/road-speed-and-journey-estimatesSun, 01 Nov 2026 00:00:00 GMTTomA route estimate uses 90 km/h while a vehicle display or planning document uses mph. Translating that speed helps readers compare like units.https://unitly.one/blog/decimal-hours-and-timesheetshttps://unitly.one/blog/decimal-hours-and-timesheetsFri, 30 Oct 2026 00:00:00 GMTTomA timesheet records one hour thirty minutes, while a spreadsheet expects decimal hours. Entering 1.30 is a tempting mistake: the decimal fraction means thirty hundredths of an hour, not thirty minutes.https://unitly.one/blog/degrees-radians-and-arc-lengthhttps://unitly.one/blog/degrees-radians-and-arc-lengthWed, 28 Oct 2026 00:00:00 GMTTomA drawing labels an angle in degrees, but an arc-length formula expects radians. The number 45 is not ready for that equation until its unit is converted.https://unitly.one/blog/density-to-mass-liquid-volumehttps://unitly.one/blog/density-to-mass-liquid-volumeMon, 26 Oct 2026 00:00:00 GMTTomA supplier gives a liquid density in g/cm³ and a container volume in litres. The mass estimate needs those values to speak the same dimensional language.https://unitly.one/blog/gauge-absolute-pressure-and-unit-labelshttps://unitly.one/blog/gauge-absolute-pressure-and-unit-labelsSun, 25 Oct 2026 00:00:00 GMTTomAn instrument reads 2.2 bar and a specification uses psi. Before converting, check the pressure reference.https://unitly.one/blog/kilowatt-hours-and-electricity-meter-readingshttps://unitly.one/blog/kilowatt-hours-and-electricity-meter-readingsFri, 23 Oct 2026 00:00:00 GMTTomAn electricity meter records an energy quantity, often in kilowatt-hours. A device label records a power rate in watts.https://unitly.one/blog/mechanical-and-metric-horsepowerhttps://unitly.one/blog/mechanical-and-metric-horsepowerWed, 21 Oct 2026 00:00:00 GMTTomTwo equipment listings both say horsepower but use different definitions. Mechanical horsepower and metric horsepower are close enough to invite casual comparison, yet they are not the same unit.https://unitly.one/blog/fuel-economy-combining-trip-recordshttps://unitly.one/blog/fuel-economy-combining-trip-recordsMon, 19 Oct 2026 00:00:00 GMTTomTwo trips can return different economy figures even when their combined fuel use is easy to measure. Averaging the two mpg numbers without weighting can give the wrong overall result.https://unitly.one/blog/frequency-period-and-clock-ratingshttps://unitly.one/blog/frequency-period-and-clock-ratingsSun, 18 Oct 2026 00:00:00 GMTTomA signal specification gives 2.4 MHz, while a timing calculation expects cycles per second. Converting the frequency is the first step; identifying the cycle being counted is just as important.https://unitly.one/blog/mass-force-and-standard-gravityhttps://unitly.one/blog/mass-force-and-standard-gravityFri, 16 Oct 2026 00:00:00 GMTTomA loading document gives a force in newtons while a scale or catalogue describes a mass in kilograms. Those quantities are connected by a physical model, not merely by changing the unit label.https://unitly.one/blog/accelerometer-g-and-axis-readingshttps://unitly.one/blog/accelerometer-g-and-axis-readingsWed, 14 Oct 2026 00:00:00 GMTTomAn accelerometer reports a value in g, but a calculation expects m/s². The unit g₀ is a standard-gravity reference, not a claim that the device measured local gravity exactly.https://unitly.one/blog/torque-wrench-newton-metres-pound-incheshttps://unitly.one/blog/torque-wrench-newton-metres-pound-inchesMon, 12 Oct 2026 00:00:00 GMTTomA torque specification is useful only when its unit survives the handoff to the tool. Pound-force feet and pound-force inches look similar on a quick note, but differ by a factor of twelve.
