<!-- from fixya rte -->What is 25 linear feet in square feet - Office Equipment & Supplies

You would need the dimensions of the item that you are trying to calculate the distance on. For example, a 12 inch by 12 inch tile is one square foot. 18 of them would be 18 square feet. If you place them end-to-end you would have 18 linear feet. However, if you had a 6 inch by 12 inch tile, it would take 36 of them to get 18 square feet. If you lined the tiles up in a row on the 6 inch side, you would have 18 linear feet. If you lined them up on the 12 inch side, you would have 36 linear feet. Linear feet does not take into account width, only length. So trying to translate a 2-dimensional value into a 1-dimensional value is difficult if not impossible without more details.

How many linear feet are there per square foot

You get square feet by multiplying linear feet with another linear feet. 18 sq.ft = 3 lin ft x 6 lin ft or 2 lin ft x 9 lin feet or 4,5 lin ft x 4lin feet.
Sq ft is used to quantify surface area where linear feet quantify distance but lin ft x lin ft gives you square ft (surface area)

A total of 63 linear inches is 5 ft 3 in, or 5.25 linear ft.

I am assuming you are talking about fencing in 3 sides of an area with each side being 25 feet long. Linear feet refers to only the running length of the fence. It doesn't care about height. For example, you fence will be 75 linear feet long...three sides each 25 feet. The price per linear foot already takes into account the fence height. For example, you say that the fence you want is about $15.00 per linear foot. For the sake of argument, say your fence is 4 feet high. If you were to change to a 3 foot high fence, the cost per linear foot would be less since there is less fencing material. If you wanted to up the height to 6 feet, the price would rise accordingly.

304.94/2 gets your linear feet = 152.47. If you want a square "room" you will have about 1450 square feet

Sounds like a math homework question. I suggest you divide the given side length into the area to obtain the second side. Add the first side and second side to get the linear feet for the two sides.....

2 Linear feet of 6" Material would make 1 Sq Ft.
so 1200 linear feet should do it.

It equals zero square feet.
Linear feet is only one dimension (length). You need 2 dimensions to calculate square feet. In other words, you need *width* also.
But IF you're asking how many square feet is 9 linear feet (long) by 9 linear feet (wide), then the answer is 81.

Linear feet are a measure of length (no different from feet); square feet measure area. You cannot simply convert between measures of different kinds of quantities;the connection between them will be specific to a particular problem.A practical example in which this question can arise is in buying countertops for a kitchen. Some materials are sold by the square foot; others (basically those that are extruded, so they come in standard widths) are sold by the linear foot. In order to compare the two, you need to compute the area and wall length for the countertop you want.You can't convert between the two. All you have to do is to make the appropriate measurements so you can calculate the price of each item.The terms used in the lumber industry are a bit confusing.There are two terms that I think you might be mixing up.A LINEAR FOOT is simply the length of a board. If you want to know the area or volume of the board,you need additional information. For instance, 6 linear feet of 1-by-12 has an area of 6 square feet (12 inches = 1 foot, times 6 feet), and it's 1 inch thick, so the volume is 1/2 cubic foot (6 square feet times 1/12 foot). But 6 linear feet of a 1-by-6 board would have half the area and half the volume.A BOARD FOOT is equivalent to one square foot of a 1-inch-thick board. In other words, it is a square-foot-inch (ft^2-in), or 1/12 cubic foot.Linear feet are used for the pricing of a single size such as two-by-fours. Board feet are used for larger lumber that you are more likely to want to compare directly with different size boards .To sum up, neither a linear foot nor a board foot can be converted directly to square feet. A linear foot is a linear (length) measure, and a board foot is a volume measure. You need to know your particular board to do anything more, such as find the area.an example with an" L" shaped countertop will betwo rectangles are 24 by 80 inches and 24 by 36 inches. Thus the area is: 24 * 80 + 24 * 36 = 24 * (80 + 36) = 24 * 116= 2784 sq. in.To get it in square feet, divide by 144:
2784 / 144 = 19.33 sq. ft.The linear measure of this countertop would be 60 + 80 = 140 inches = 140/12 feet = 11.67 feet
