The highest mountain in Canada, Mount Logan has a total height of 5,960 m. The high altitude and northern latitude of the mountain resulted in one-time temperature of -77.5 °C — the lowest temperature ever recorded outside of Antarctica.
It's about one-and-one-fifth times as tall as a Kilimanjaro.
In other words, 6,800 meters is 1.154340 times the height of a Kilimanjaro, and the height of a Kilimanjaro is 0.8662960 times that amount.(a.k.a. Mount Kilimanjaro) (Tanzania) (to Uhuru peak; 2008 gravimeter measurement)
