About this converter
The Defense Force grades every kaiju to one decimal and the scale tells the story. Philinosoma at 6.0, Crustacean-type at 6.2, Polyonax at 6.4, Mixogastero at 7.1, Diclonius at 7.2, Anguilla at 7.3, Third Wave at 8.0, No. 10 at 8.3, No. 9 at 8.5, No. 15 and No. 1 at 9.0, No. 13 at 9.2, No. 9 absorbed at 9.5, No. 6 at 9.6 and Kafka at 9.8. No. 10 injured at 5.7 proves readings fall with damage, which the table notes per row. Daikaiju starts above 8.0 and identified numbers start at 9.0, so the table reads like a promotion ladder. Every value here is a printed manga reading.
How to use it
Pick two kaiju and the unit in the top row. The three boxes below stay linked: one holds a count of the first, one the matching count of the second, one the total in fortitude. Change any box and the other two update. Try 1 Kafka against Philinosomas.
Evolved Kafka reads unmeasurable and stays out as its own row. No. 10 injured at 5.7 shows readings move with condition, noted per row. Meireki era daikaiju lack modern readings and stay out. Yoju below 6.0 were never given fixed numbers and stay out.
