                In ancient times, people measured the length, weight, and capacity of objects using
                natural and body-based units like seeds, fingers, palms, and steps, as there were no
                specified units or standardised tools.

                Today, we use standard units for measurement: length is measured in millimetres
                (mm), centimetres (cm), metres (m) or kilometres (km), mass (weight) is measured
                in grams (g) or kilograms (kg), and capacity is measured in litres (L) or millilitres (mL).
