Final answer:
The highest recorded temperature in the world is 134°F (56.7°C) in Death Valley, California. The previous record held by El Azizia, Libya of 136°F was invalidated due to measurement concerns.
Step-by-step explanation:
The highest recorded temperature in the world was 56.7°C (134°F) in Death Valley, California, USA, on July 10, 1913. Previously, the record was believed to be 58.0°C in El Azizia, Libya, on September 13, 1922, but this record was invalidated by the World Meteorological Organization in 2012 due to concerns about the reliability of the measurement. Therefore, when converting 136°F to Celsius, it would be approximately 57.8°C, which is close but not the official highest temperature. Converting the Death Valley temperature of 134°F to Celsius gives us about 56.7°C, and in kelvins, it is approximately 329.85 K.
