1 metre.
Square meters cannot be converted into linear meters; square meters are units of are and linear meters are units of length.
The term lineal meter is used to describe the nominal length of an item. For example carpet maybe produced on a loom perhaps 4m wide. A lineal meter of carpet would be 1m long x 4m wide. Thus 4 lineal meters of this particular carpet would cover 16 square meters. In a similar fashion timber is often sold by the lineal meter which describes the cost per meter of length of the board. The board would have a width and if you were to the purchase timber to build a deck you would need to calculate the number of lengths of boards to cover the area of deck having taken into account the width of the board. When ordering you would ask for X lineal meters of the particular board. Obviously its important to know the particular specifications of the material you intend to use. For example not all carpet is produced on a 4m loom and so it is important to understand the effect of substituting different materials so that a material shortage or wastage does not occur.
Exactly one. They are the same thing!
You cannot convert meters to square meters. A meter measures length or distance. A square meter measures area.
A PHCN meter measures electric power for prepaid meters in Nigeria.
A stick that measures meters.
The answer will depend on the standard width(s) in which the carpet is made (or priced).
The answer will depend on the width of the decking boards.
There is no rational answer because you are talking about two completely different things. A meter is a lineal distance measurement. A square meter is an area measurement. If I am driving to the store, I will measure my distance with a lineal measurement, as an example there are 4,358 meters from my house to the store, but there are not (technically) 4,358 square meters unless you drew the line from my house to the store 1 meter wide. 1 square meter has a lineal distance measurement "around" the square of 4 meters. Pick a corner and pretend the square is a fenced in yard. In order to start in one corner and walk all the way around the fence, you will have to walk 4 meters, so you may be able to say that 1 square meter has a "perimeter" of 4 meters.
One meter.
As a linear meter is a length with zero width, even with an infinite number of them they will not cover an area of 30 square meters.
one meter. lineal refers to length
