How is a rain-affected cricket target calculated?

The DLS method compares the resources (overs and wickets) each team had. The second team’s target is scaled to its share of resources.

What is a perfect bowling score?

300: twelve strikes in a row, including the two bonus rolls in the tenth frame.

Why is 6.1 innings not 6.1 in the ERA formula?

In baseball notation the decimal counts outs, so 6.1 means 6⅓ innings. Treating it as a decimal gives the wrong ERA.

Which Wilks formula do you use?

The original 1994 Wilks formula, which many federations used before newer systems such as DOTS and IPF GL points.

Scoring and rules

Several sports use scoring rules that are hard to apply in your head. The Duckworth-Lewis Calculator resets cricket targets after rain interruptions using the resources each team had available. The ERA Calculator handles baseball’s innings notation, where 6.1 means six and one-third innings. The Bowling Score Calculator applies strike and spare bonuses frame by frame, and the Bowling Handicap Calculator works out league handicaps from your average.

For combined events, the Decathlon and Heptathlon Calculators use the official World Athletics scoring tables, and the Wilks Calculator compares powerlifting totals across bodyweights using the original Wilks formula.

Pacing and training

Endurance athletes plan by pace. The Swim Pace Calculator converts times into pace per 100 m or 100 yd, the Cycling Speed and Cycling Cadence Calculators connect speed, gearing, and pedal RPM, and the Triathlon Calculator adds up swim, bike, run, and transition splits or works backwards from a target finish time.

Equipment

The Golf Club Length Calculator suggests a length adjustment from your height and wrist-to-floor measurement. The Arrow Speed Calculator estimates arrow speed, kinetic energy, and momentum from your bow’s IBO rating and setup, and the Boat Speed Calculator estimates speed from hull length or propeller specifications.

Key formulas

Earned Run Average: ERA = earned runs × 9 ÷ innings pitched
Bowling handicap: (base average − your average) × handicap %
Displacement hull speed: knots ≈ 1.34 × √(waterline length in ft)
Arrow kinetic energy: ft-lbs = grains × fps² ÷ 450,240

Getting accurate results

Enter innings pitched in baseball notation (.1 and .2 are thirds of an inning, not tenths).
Use your established league average for bowling handicaps, and the base average and percentage your league sets.
For combined events, enter jumps in metres; the calculator converts them as the scoring tables require.
Measure wrist-to-floor in your normal athletic shoes for golf club fitting.
