How much rice do you eat??

there is a dispute within the kaibigans...of how much rice we eat...it started when we were trying to decide how much rice to bring for our Aussie break Away...(yes we are poor that we have to cook our own meals)

ignore the beras pulut...the pack we plan to bring are the 1kg rice packets....so we wanted to know how much rice should we bring for a 10 days self cater trip....with 6 Dugongs (eh ada juga ikan bilis ikut...mereka yg kurus..dan yg menafi mereka  byk makan nasi)..

so our engineer was saying 1kg is almost equavalent to 8 put/kong/cups or watever you call this little cup..

 these are cups that comes with the ricecooker....i bet we all have different names for it......i think i learn to cook with this cup when i had my own house...with the rice cooker my mom gave...cos it came with a cup...
at home we had this stainless steel tin...the susu cap junjung tin....like these ones..

we call it kong...!and please be reminded this kong is 2 cups..rice cooker cups....i remembered one time when i was in primary 6...my mom shouted from the garden to ask me to cook porridge...and i shouted back from the kitchen to ask her how many cups....i said CUPS...so she said 2....but actually in the rice bin (we use  to use baldi back then...was this "kong". so i cook 2 kong....back then my late grandfather was with us...so during dinner he asked my mom "i tot you said you cook porridge...?"- we had  rice that evening...hehee..!as i put 2 kong of rice in a small pot with the same amount of water and you got rice instead of porridge....(my mom tot i was using the small cup measurement...!"

back to the argument....some of us were saying 1 kong/put/pot/cup will be able to feed 4 person or even the whole group the 6 of us...and some say  1 kong/put/pot/cup is so little rice..this 2 days i did an experiment...with the bro and me..i cook with 1 cup...and we had plenty until i couldn't stand up..!! the bro was complainning of his mountain like rice in his plate...!but if i cook something that was our favourite the rice was just enough...

so well...please help do maths and say how many kilos of rice should we bring...!! :P
