cmBody measurements, height and international valuesInch, foot, centimetre and metre values mix constantly in clothing, height, sports profiles and international forms.GiBIT storage, cloud limits and data sizesGB, GiB, MB, MiB, byte and bit decide whether storage plans, upload limits and RAM values are truly comparable.kWhEnergy prices, kWh and technical workkWh is practical on bills, joule is precise in physics and engineering. UnitCloud connects both without mixing power values.psiTyre pressure, bar and psiVehicle manuals, pumps and tyre pages switch between bar, psi and kPa. This guide shows factor, table and typical rounding.mlKitchen, cups, millilitres and recipe valuesCups and millilitres are volume. Dry ingredients also need density or a recipe source.ppiPrint, pixels, megapixels and PPIMegapixels describe area, not print size. Clean print sizing needs pixel edges, PPI and target medium.ptTypography, CSS pixels and point sizespx, pt and mm look similar but come from web, print and physical length. The source decides the right interpretation.NmTorque, workshop values and spec sheetsNm and ft lb appear together in tools, bicycles, cars and engineering. Unit and direction must stay clear.g/cm3Density, material values and reference tablesg/cm3 and kg/m3 separate lab values, material tables and simulations. The factor is simple, the meaning is not.HzFrequency, rotation speed and signal valuesHz and rpm connect oscillation, motors, fans and signals. Per second and per minute must not be mixed.m2Construction, workshop, area and volumeLength, area and volume must stay separate in construction. A length factor becomes squared for area and cubed for volume.SISchool, study and SI fundamentalsUnit conversion becomes easier when base quantity, factor, formula and common mistake are always visible together.
