Of course, because our handwriting isn’t always as good as a computer’s typing, it’s too easy to write both Phi and Theta as Ø. Today, both Phi and Theta are used in various disciplines to show function, phase, or angle. Also, the line is horizontal and stays within the 0. And with Theta, it looks more like a 0 than an O. In the Greek alphabet, they have Phi (ϕ) and Theta ( θ).Īs you probably already noticed, with Phi, the difference is the circle is smaller and the liner goes vertically. “Hey Mark, how many guests have you booked?”Īnd the final meaning of Ø isn’t a meaning at all.
Please add money or the account will be shut down”. It might also be beneficial when you have to use “O” and “0” in the same sentence. This kind of zero might be used when it’s important to know there is nothing there, for example, when talking about banking. Therefore, having a Ø instead means there is no confusion. Particularly if it’s written out by hand. The trouble with “0” is it looks like “O”. Staying on the topic of Mathematics, another use for Ø is a zero. “A cat with intestines which are Ø8 mm and a throat Ø10 mm would likely receive a 10 mm diameter tube” O with line through it meaning “Empty” or “None” “Usual sizes for these tubes are an inner Ø1-3 nm and an outer Ø of around 10 nm.” “It has to be Ø14 mm or more, but it can’t be more than 19 mm” Therefore, using a Ø helps people know what that number is without making it too complex. Often, people wouldn’t write the word “Diameter” because it’s too long, or “D” because that could stand for anything. In a circle, half of the diameter is known as the radius. It’s the distance from one end of a shape to the other, and it must pass through the center of that shape. 12 words in Nordic languages that use O with line through itĬause in Faroese O with line through it meaning diameterīut, back in English, or more like Mathematics, the symbol Ø can also be used when measuring the diameter of something.įor those who haven’t sat in a Maths classroom for some years, a diameter is a measurement taken from a shape. In other languages, Ø might be written as œ. In many European languages, they have the same alphabet that we do, but a few more letters dropped in there.
Because Ø means OE, and cannot be swapped for an “O”. When you see Ø, be careful not to get it mixed up with “O”. The first example of what Ø means is its a letter in some Nordic languages. Watch the video: Only 1 percent of our visitors get these 3 grammar questions right.
