My answers are correct:

It helps to know what the terms mean. mg means milligram, and this literally 1/1000th of a gram. Any unit in grams multiplied by 1000 gives mg. So 12.8 times 1000= 12800 mg.

A kg is a kilogram, or 1000 grams. So if we have 68.2kG, we have 68.2 times 1000, or 68,200g

A cm is 1/100th of a meter. 15.4 centimeters divided by 100=

.154m

A Liter (L) is 1000mL, milileters. So 11.5L=11500mL

A meter has 100 cm, so 1.1m x100= 110cm

The other answers all contain errors.

12.8g = 128mg

68.2kg = 6820g

15.4cm = 0.154m

11.5L = 1150mL

1.1m = 110cm

Whoa! That was fun!
