The calculation process of construction measure was cumbersome with complex and heavy workload. Using a computer program can save a lot of manpower, improve work efficiency and reduce the error rate calculated. The article introduced the characteristics of plural and measure coordinate system. With good combination and transformation between plural and measure coordinate, so that the plural of four operations, functions and other functions were easily applied to the measurement coordinate program calculations，variables can be saved and simplify procedures, application prospect would be wide.
