Abstract: This paper shows how weight estimates, Japanese Agricultural Standard (JAS) volume, true volumeto- weight conversion and scaling affects JAS/tonne values. Three years of data collected from a port and weighbridge operations are used to show the magnitude of changes in JAS/tonne values. It is concluded that JAS and basic density have a significant effect on JAS/ tonne. There is also a statistically significant change in truck tare weight by season and time of day. Therefore load weight based on estimated tare also affects the JAS/ tonne ratio.
