A contravariant tensor is a Tensor having specific transformation properties (c.f., a Covariant Tensor). To
examine the transformation properties of a contravariant tensor, first consider a Tensor of Rank 1 (a Vector)

Covariant Tensors are a type of Tensor with differing transformation properties, denoted
. However, in 3-D Cartesian Coordinates,

To turn a Covariant Tensor into a contravariant tensor, use the Metric Tensor to write
