The fuel gage of the present invention uses a combination of (i) one or more load cells or fuel level measuring devices, plus in some cases other sensors which measure the pitch or roll angle of the vehicle or the fuel density, to approximately measure the quantity of the fuel in the tank and (ii) a processor and algorithm, which may be a look-up table or formulae, to correct for the inaccuracies arising from the pitch and roll angles of the vehicle, other external forces or from variations in fuel density. Although several weighing systems are disclosed for illustrative purposes, the invention applies to any method of making an approximate measurement of the fuel quantity (weight or volume) and then using analytical techniques to improve on the measurement.

A fish net in accordance with claim 2, wherein the length measuring scale includes length markings representing modified units of length to compensate for curvature of the fish and the length measuring scale. 4. A fish net in accordance with claim 2, wherein the net forms a pocket in which the fish naturally tends to rest in substantial linear alignment with the length measuring scale. 5. A fish net in accordance with claim 2, wherein the frame further comprises a substantially closed loop portion having opposing sides, and the length measuring scale extends from one side of the closed loop to the opposing side. 6. A fish net in accordance with claim 2, wherein the net further comprises: a. first and second side pieces with curved edges; b. a substantially linear center piece, having side edges, the length measuring scale being disposed on the center piece; and c. the side edges of the center piece being connected to the curved edges of the first and second side pieces, forming a pocket in which the fish naturally tends to rest in substantial linear alignment with the length measuring scale. 7. A fish net in accordance with claim 6, wherein the first and second side pieces and the center piece are of the same material. 8. A fish net in accordance with claim 6, wherein the first and second side pieces and the center piece are of different materials. 9. A fish net in accordance with claim 6, wherein the center piece is of a material selected from the group consisting of: mesh and net materials of cotton and polymers. 10. A fish net in accordance with claim 2, wherein the net is of a material selected from the group consisting of: mesh and net materials of cotton and polymers. 11. A fish net in accordance with claim 2, wherein the length measuring scale is disposed on the net by a process selected from the group consisting of: weaving into the material of the net; embroidering onto the material of the net; printing on the material of the net; and silk-screening onto the material of the net. 12. A fish net in accordance with claim 2, wherein the frame further comprises: a. a handle; and b. a substantially closed loop portion, attached to the handle, the net being attached to the loop portion. 13. A fish net, comprising: a. a frame having: i. a handle; and ii. a substantially closed loop portion, having opposite sides, attached to the handle; b. a net, attached to the loop portion, having a bottom and a top; and c. a length measuring scale, having length markings with numeral designations representing units of length, disposed generally linearly on the net and extending from one side of the loop portion to an opposing side thereof, the length markings including a zero point near the bottom, with two coordinated scales sharing the zero point and extending in opposing directions therefrom to the top of the net, the net forming a pocket into which a fish naturally tends to rest in substantial linear alignment with the measuring scale, such that a user may determine a size of the fish held in the net by visually comparing the fish with the numeral designations on the length measuring scale and adding the numeral designations which are approximately aligned with opposing ends of the fish. 14. A fish net in accordance with claim 13, wherein the length measuring scale includes length markings representing modified units of length to compensate for relative curvature of the fish and the length measuring scale. 15. A fish net in accordance with claim 13, wherein the net is of a material selected from the group consisting of: mesh and net materials of cotton and polymers. 16. A fish net in accordance with claim 13, wherein the length markings represent standard units of length. 17. A method of measuring a size of a fish, comprising the step s of: a. placing a fish within a fish net having a frame and a net having a top and a bottom, and a length measuring scale disposed on the net, the length measuring scale including a zero point approximately at a bottom of the net, and two coordinated scales with numeral designations sharing the zero point and extending in opposing linear directions therefrom to the top of the net; b. aligning the fish with respect to the length measuring scale; and c. visually comparing the fish to the length measuring scale by adding the numeral designations which are approximately aligned with opposing ends of the fish, so as to determine a size of the fish. 18. A method in accordance with claim 17, wherein the step of placing the fish within the fish net further comprises causing the fish to rest in a bottom of the net in substantial linear alignment with the length scale.
