Conversion guides

Go beyond a single conversion. These guides compare related formats and units, work through examples, and let you try the relevant converter without leaving the page.

Mass

MassKilograms, pounds, stones and tons: which mass unit is meant? Compare kg, lb, st, metric tonnes and US short tons while avoiding ambiguous ton labels.Read guide

Temperature

TemperatureCelsius, Fahrenheit and Kelvin: choose the right conversion Compare temperature scales, offsets and intervals with a worked Celsius–Fahrenheit–Kelvin example and avoid common formula mistakes.Read guide

Area

AreaSquare metres and square feet: why the length factor must be squared Calculate room area from dimensions, convert m² to ft², and avoid applying a length factor to a surface.Read guide AreaHectares, acres and square miles: read land area correctly Compare hectares, acres, square kilometres and square miles without confusing a parcel with a region.Read guide

Volume

VolumeUS vs Imperial gallons and fluid ounces Compare US and Imperial liquid gallons, understand the fluid-ounce trap, and convert liters with a worked example.Read guide VolumeUS cups, milliliters and fluid ounces in recipes Convert US customary cups to milliliters, understand recipe rounding and avoid confusing liquid volume with ingredient mass.Read guide

Speed

SpeedNautical miles and knots: compare distance with road speed Learn why a knot is a nautical mile per hour, convert to km/h and mph, and estimate a trip without confusing distance and speed.Read guide

Time

TimeDecimal hours vs hours and minutes: read a timesheet correctly Convert elapsed minutes to decimal hours and distinguish durations from clock times and calendar days.Read guide

Pressure

Pressureatm, bar, kPa and psi: convert the unit and check the reference Compare common pressure units while keeping gauge and absolute pressure readings distinct.Read guide

Energy

EnergykJ, kcal and BTU: read energy numbers in context Compare kilojoules, food kilocalories and IT BTU with a worked label example and careful treatment of rounding and serving size.Read guide

Power

PowerWatts, kilowatts, horsepower and kWh: power is not energy Distinguish instantaneous power from energy over time, with a worked kW, hp, kWh and MJ example.Read guide

Digital storage

Digital storageMB vs MiB: why storage numbers differ Understand decimal and binary storage units, work through an exact example, and compare MB, GB and TB with MiB, GiB and TiB.Read guide

Angle

AngleDegrees, radians and turns: choose the right angle unit Connect degrees, radians and turns through a quarter rotation and avoid unit mistakes in trigonometry.Read guide

Fuel economy

Fuel economyL/100 km vs US and Imperial mpg Convert fuel consumption with the reciprocal formula, compare US and Imperial mpg, and avoid misleading averages.Read guide
