Mass / Weight Converter

In Portugal we use Kilograms.
Sometimes I use cups instead of Kilograms, so I made this short converter table:


1 Cup = 1/4 of Liter = 1 Water Glass

1 Cup of Sugar = 210 grams (gr)

1 Cup Flour = 100 grams (gr)

1 Cup of Butter = 180 grams (gr)

1 Cup of Rice = 180 grams (gr)
