` = "Spikes per Pound"`
Enter a value for all fields
The Spikes per Pound calculator computes the number of common bright spikes based on the size and gross weight of the spikes .
INSTRUCTIONS: Choose units and enter the following:
- (G) Spike Guage (choose: 5/16" or 3/8")
- (L) Spike Length (choose: 7", 8", 10", 12", 14")
- (W) Weight of Spikes (default: 10 lbs)
Number of Common Spikes (nS): The calculator returns the number spikes.
The Math / Science
The Spikes Per Pound equation computes the weight of the spikes as follows:
SW = nN * WPN
where:
- SW = Weight of the Spikes
- nN = Number of Spikes
- WPN = Weight per Spike
Common Spike (Bright) Information
| Common Spike Information |
