Sports calculators

Use a timed pendulum test to estimate a baseball or softball bat swing weight at the standard six-inch axis. Add optional tape, a knob weight, or an end load to see the predicted change before modifying the bat.

Choose a standard diamond or enter custom dimensions to turn a baseball field layout into tape distances and compass-oriented stake coordinates. The result includes diagonal checks, pitching-plate offset, symmetric fence geometry, and a practical stakeout sequence.

Enter a pitching line to see the original Bill James Game Score and Tom Tango Game Score v2 side by side. The calculator treats 6.1 and 6.2 innings as one or two outs, not decimal innings.

Enter your power, bike setup, road grade, wind, and distance to estimate steady cycling speed. You can also switch the calculation around to find the crank watts needed for a target speed.

Enter each player Handicap Index and the tee ratings to calculate the recommended scramble allowance. The tool ranks the players by Course Handicap, applies the team-size percentages, and shows the net score from the gross scramble score.

Enter the measured club weight, balance point, target swingweight, and the spot where you plan to add or remove weight. The calculator solves the 14-inch-fulcrum swingweight equation backward and checks the projected balance point.

Use consistent collar and pin measurements to examine a sculling or sweep rig. The calculator can also work backward from a target gearing ratio or handle overlap.

Enter the track radius, straight length, lane width, lane count, and bend count to lay out the start offsets for each lane. The table shows the stagger distance, survey angle, chord check, and measured lap length for every lane.

Enter the field size, line width, paint coverage, and number of applications. The calculator checks the dimensions, totals the full-size soccer markings, and turns the line area into ready-to-apply paint and containers.

Enter the event, sector length, field width, and station spacing to get the cross-tape measurements for a regulation 34.92-degree throwing sector. The table gives the full width and centerline offset at each marking station.
