What is the formula that EIGRP uses in scaling the bandwidth,delay,total metric?

EIGRP adds together weighted values of different network link characteristics in order to calculate a metric for evaluating path selection. These characteristics include:

• Delay (measured in10s of microseconds)

• Bandwidth (measured in kilobytes per second)

• Reliability (in numbers ranging from1 to255;255 being the most reliable)

• Load (in numbers ranging from1 to255;255 being saturated)

Various constants (K 1 through K 5) are able to be set by a user to produce varying routing behaviors. However by default, only delay and bandwidth are used in the weighted formula to produce a single32bit metric:
