Some­times, we want to add a degree sign to num­bers. How can we do it? 

Add degree sign (°C) to numbers

Let’s say we want to show tem­per­a­ture in degrees Cel­sius or Fahren­heit. The first thing we want to do is insert­ing the cor­rect sign. We can either copy it from the inter­net or we can choose the Sym­bol com­mand from the Insert tab (Fig. 1).

In the Sym­bol win­dow that appears, we’re choos­ing the Latin‑1 Sub­set (1), then the Degree Sign, whose name we can see at the bot­tom of this win­dow. We click the Insert and Close but­tons (Fig. 2).

We can see the Degree Sign in cell D1. After adding C, we have the full sym­bol. Now, we can copy the sym­bol in the edit mode, then select all cells with num­bers to which we want to add the sign. Then, we press the Ctrl + 1 short­cut. In the For­mat Cells win­dow we’re choos­ing the Cus­tom Cat­e­go­ry, then we’re choos­ing 0 and we can paste the °C sign. In the Sam­ple bar we can pre­view what our final text will look like in the end. If we want to make sure that our text will be show as a text in the end, we can write it in dou­ble quotes. In this case, it’s a bul­let­proof solu­tion (Fig. 4).

And we have our signs cor­rect­ly insert­ed (Fig. 5).
