单位净值是指基金公司公布的基金净值，是基金的价值体现。它反映了基金的收益水平，也是投资者衡量基金投资价值的重要指标。

单位净值的计算公式为：单位净值 = 总净值 / 发行总份额。其中，总净值是指基金公司所拥有的全部资产减去全部负债后的余额，而发行总份额则是基金公司发行的基金单位总数。

对于投资者来说，单位净值的高低并不是选择基金的唯一标准。投资者还需要考虑基金的历史业绩、基金经理的投资能力、基金的投资方向等因素。同时，投资者还需要注意基金的费用情况，如管理费、托管费、销售服务费等，这些费用也会影响基金的净值。

总之，单位净值是基金公司公布的基金净值，是投资者衡量基金投资价值的重要指标。投资者在选择基金时需要综合考虑多种因素，以便做出更为明智的投资决策。
