Drag the measuring gauge to convert metric units — mm·cm·m, g·kg, mL·L. The level you fill IS the answer.
Each round asks a child to drag a gauge to the correct fill level, converting between millimetres and centimetres, grams and kilograms, or millilitres and litres — the position of the gauge at that point is the answer made visible. The practice builds fluency in metric units, measurement relationships, and conversion across length, mass, and volume. Best for Grades 3–6, or anyone working through metric measurement for the first time.
A free, no-signup, no-ads math game for Grades 3–6 — practising units, conversion, metric, measurement. Play in your browser on the KidsDoMath games hub or explore more Measurement games.
