Ants are 5mm, marathons are 42km πŸ“ Place objects on a 20cm ruler and read the millimeter ticks β€” object tips snap right onto the lines. πŸ”„ In Unit Converter, see the same length in mm, cm, m, and km all at once. An ant in km is 0.000005km! That’s why choosing the right unit matters. 🎯 In Challenges, convert units, pick the best unit, and guess which is longer β€” comparison bars are hidden, so convert first, answer, then check with the bars.
