1 Metric ton tonne is equal to 1000000 grams g. To convert tons to grams multiply the ton value by 1000000. For example to find out how many grams in a ton and a half multiply 1.5 by 1000000 that makes 1500000 grams in a ton and a half. 1 Gram g is equal to 0.000001 metric ton. To convert grams to metric tons multiply the gram value
