Conversion For Distance Events
400/800 meters (long course) converts to 500/1000 yards by dividing meter
time by .8925.
1500 meters (long course) converts to 1650 yards by dividing meter time by
1.02.
500/1000 yards converts to 400/800 meters (long course) by multiplying by
.8925.
1650 yards converts to 1500 meters (long course) by multiplying by 1.02.
To convert Long Course Meters to Short Course Meters use the following
formulas for distance events:
400 freestyle: long course time - 6.4 seconds = short course meters time.
800 freestyle: long course time - 12.8 seconds = short course meters time.
1500 freestyle: long course time - 24.0 seconds = short course meters time.
Altitude Adjustment
Event Distance 3000-4250 ft. 4251-6500
ft. Above 6500 ft.
200 .50
Sec 1.20 Sec 1.60 Sec
400 or 500 2.50
Sec 5.00 Sec 7.00 Sec
800 Free Relay 2.00 Sec 4.80
Sec 6.40 Sec
800 or 1000 5.0 Sec 10.00
Sec 15.00 Sec
1500 or 1650 11.00 Sec 23.00
Sec 32.50 Sec
Subtract the time indicated above from the actual time achieved at that
altitude. This is the time to be used on the entry form and seeding will
be based on that time. Information relative to the adjustment must be
shown in a seperate statement accompanying the entry form. This statement
must include the name of the swimmer, event, date of performance, elevation
location, actual time, corrected time, and signature of coach or person
certifying the entry.
