Graphene used to redefine the Kilogram and Ampere units

Scientists suggest a new way to measure the Kilogram and Ampere units - using Graphene. These units can be measured using the quantum hall effect, and they suggest the Graphene may be the best conductive material for the job - it can be used to measure the units up to an uncertainty of just 86 parts per trillion.
