(Long Course Meters to Short Course Meters: Just subtract seconds) |
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. |

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. |
