In this paper, we are concerned with energy equality of weak solutions to the electron magnetohydrodynamic equations. In the spirit of Cheskidov and Luo’s and Berselli’s works, it is shown that weak solutions in \(L^{2/\alpha ,\infty }(0,T;C^{\alpha }(\mathbb {R}^{3}))\) with \(0\le \alpha <1\) satisfy energy equality in this system. In addition, we prove that magnetic helicity identity holds if weak solutions H satisfy \(H\in L^{ {2}/{(\alpha +1)},\infty }(0,T;C^{\alpha }(\mathbb {R}^{3}))\) with \(0<\alpha <1\) . This indicates that the conservation of magnetic helicity is easier than that of energy and agrees with the Taylor conjecture in magnetohydrodynamic turbulence.
