About this converter
Tennis serve speeds top out where radar guns meet tall shoulders. Sam Groth 263.4 km/h at Busan 2012 is the fastest ever recorded and the Guinness mark, though it came at a Challenger with non tour radar. Albano Olivetti 257.5 km/h in the same year sits second. John Isner 253 km/h in Davis Cup 2016 is the fastest ATP recognized serve. Karlovic and Janowicz tie at 251. Raonic 249.9, Roddick 249.4 and Guccione 248 stack the 2012 and mid 2000s era of giants. Johansson, Lopez and Perricard tie at 244.6 across grass and clay. Dent 241 closes the table. Speeds follow the Wikipedia fastest serves table with Guinness and ATP notes on recognition.
How to use it
Pick two servers and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. One box holds a count of the first server, one holds the matching count of the second, one holds the speed in the chosen unit. Try 1 Groth against Dents to compare top against floor.
Speeds are single fastest recorded serves, not averages. Challenger radar differs from tour systems, so Groth and Olivetti sit outside ATP recognition and are labeled.
