To convert the given distance into meters, we need to convert all the units to meters and then add them together. 1 km = 1000 meters 2 m = 2 meters 3 mm = 0.003 meters (since 1 mm = 0.001 meters) Adding these together, we get: 1000 meters + 2 meters + 0.003 meters = 1002.003 meters So, 1 km 2 m and 3 mm is equal to 1002.003 meters.
