Fabric Cover Factor
Compute a fabric's cover factor, CF = thread density (threads/cm) · √(Tex), an index of how 'closed' the weave is — how much the threads cover the area, leaving more or fewer open spaces. High factors indicate dense, opaque fabrics (canvas, twill); low ones, sheer, breathable fabrics (voile, mesh). It influences air permeability, opacity and strength. Enter the thread density and the count in Tex.

Fator de cobertura do tecido
O fator de cobertura traduz num número o quão 'fechado' é um tecido — o quanto os fios efetivamente cobrem a área, deixando mais ou menos espaços abertos entre eles. Ele combina os dois fatores que determinam isso: a densidade de fios (mais fios, mais cobertura) e a grossura do fio (fios mais grossos cobrem mais), via FC = densidade·√(Tex). Tecidos de cobertura alta são densos, opacos e pouco permeáveis ao ar — lonas, sarjas, gabardines, ideais para vento e durabilidade. Cobertura baixa dá tecidos ralos, leves e respiráveis — voile, tela, musselina. O fator de cobertura prevê permeabilidade ao ar e à água, opacidade, resistência e até o comportamento na tinturaria. Informe a densidade de fios e o título em Tex.

Fabric Thread Count
Compute a woven fabric's thread density by adding the warp threads (lengthwise) and weft threads (widthwise) per centimeter. It is an indicator of construction and quality: higher density usually means a firmer, more durable and fuller fabric. It appears on spec sheets as 'threads/cm' or 'thread count'. Enter the warp and weft threads per cm.
Reservoir Recovery Factor
Compute a reservoir's recovery factor, RF = (Np/N)·100%, the fraction of the original oil (N, or OOIP) that will actually be produced (Np). It is one of the most important — and uncertain — numbers in the industry: primary recovery (natural energy) is usually 5–15%; with secondary recovery (water/gas injection) it rises to 30–50%; and advanced methods (EOR) can go further. It defines the field's economic value. Enter the cumulative production and the original oil in place.
Fabric Weight (GSM)
Compute a fabric's weight in grams per square meter (GSM) by dividing a sample's mass by its area. It is the main measure of fabric 'weight': light T-shirt knits are 140–180 g/m², sweatshirts 280–340, canvas and denim much more. GSM defines hand, drape, durability and price, and is specified in almost every textile spec sheet. Enter the sample's mass and area.
