Short answer: tesla (symbol T).

Clarification: what’s often called the magnetic field around a current-carrying wire is the magnetic flux density B, whose SI unit is the tesla. The related quantity magnetic field strength H has SI units ampere per meter (A/m). For a long straight wire in vacuum, B = μ0 I / (2πr) (μ0 = 4π×10^−7 N/A^2).
