About Converting Ronnajoules to Exajoules
Ronnajoule and Exajoule both measure energy, and the conversion is especially useful for comparing nutrition labels (kilocalories) against scientific energy figures (joules). Specifically: Ronnajoule is 1e+27 joule units, and exajoule is 1000000000000000000 joule units.
Formula
exajoules = ronnajoules × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 ronnajoule equals 1e+27 base units, and 1 exajoule equals 1e+18 base units, so dividing one by the other gives the direct ronnajoule-to-exajoule factor of 1000000000.
Simple example
1 RJ × 1000000000 = 1,000,000,000 EJ
1 ronnajoule = 1,000,000,000 exajoules.
Real-world example
100 RJ × 1000000000 = 100,000,000,000 EJ
100 ronnajoules = 100,000,000,000 exajoules.
