Start with a familiar distance or jump from human scale to planetary scale. Every page opens the same visualizer at a verified value.

Everyday and walking

  1. What does 100 metres look like?A 100-metre distance is the length of the standard outdoor sprint straight. It is short enough to see end to end, but long enough for a fast runner to need several seconds to cross it.0.1 km
  2. How far is 500 metres?Five hundred metres is half a kilometre. In a dense city it can span several blocks, while vertically it sits close to the height range of the tallest skyscrapers.0.5 km
  3. How far is 1 kilometre?One kilometre equals 1,000 metres or about 0.621 miles. It is a familiar neighbourhood distance and a useful baseline for larger journeys.1 km
  4. How far is 5 kilometres?Five kilometres is a common road-race distance. It reaches beyond a single neighbourhood and is long enough for terrain and route choice to noticeably change travel time.5 km
  5. How far is 10 kilometres?Ten kilometres equals 10,000 metres or roughly 6.21 miles. It is a substantial run and a cross-city trip in many urban areas.10 km

City and regional

  1. How far is 20 kilometres?Twenty kilometres is close to a half-marathon but still 1.0975 kilometres short of the official race distance. It often represents a long commute across a metropolitan area.20 km
  2. How far is a marathon?The official marathon distance is 42.195 kilometres, or about 26.219 miles. The unusual final 195 metres are part of the standardized race length.42.195 km
  3. How far is 100 kilometres?One hundred kilometres equals 100,000 metres or about 62.14 miles. It is a regional journey rather than a local trip.100 km
  4. How far is 500 kilometres?Five hundred kilometres is about 310.69 miles. It is comparable with the north-to-south extent of South Korea used in ScaleTrip's reference data.500 km
  5. How far is 1,000 kilometres?One thousand kilometres is about 621.37 miles. It crosses countries and can no longer be understood well through buildings or city blocks.1,000 km

Earth and space

  1. How large is Earth's radius?ScaleTrip uses 6,371 kilometres as a rounded mean Earth radius. A radius runs from Earth's centre to its surface; it is not the same as diameter or circumference.6,371 km
  2. How far is Earth's circumference?Earth's equatorial circumference is approximately 40,075 kilometres. It is the distance around the equator, not a straight line through the planet.40,075 km
  3. How high is geostationary orbit?Geostationary orbit is about 35,786 kilometres above Earth's equator. The value is altitude above the surface, not distance from Earth's centre.35,786 km
  4. How far is the Moon from Earth?The average centre-to-centre Earth–Moon distance is about 384,400 kilometres. The real distance changes because the Moon's orbit is not a perfect circle.384,400 km
  5. How wide is the Sun?ScaleTrip uses about 1,392,000 kilometres for the Sun's diameter. Diameter measures across the Sun through its centre and is twice the listed radius.1,392,000 km
  6. How far is Earth from the Sun?The average Earth–Sun distance is about 149.6 million kilometres, defined approximately by one astronomical unit. Earth's elliptical orbit makes the actual separation vary.149,600,000 km
