Learn how to switch kg vs lb, W vs W/kg, and km vs mi in N+One, then verify body mass, rides, plans, and exports after the change.

To change locale and units in N+One, go to Settings → Units. Displays change, while stored raw workout values stay stable.
Unit settings shape what you see during rides, in charts, and inside training-plan views. They do not need to change your stored ride files or the raw values behind past workouts. The clean move is simple: match displays to the devices you use most, then verify derived fields before you trust comparisons.
Use watts when you need a clear target for intervals, tests, and repeatable efforts. A watt value stays the same no matter which weight unit you show elsewhere in the app.
Use W·kg when the question is about power relative to body mass. That view helps when you compare riders, climbs, or athlete profiles, but it depends on the stored body-mass value.
If your power data looks off after a unit change, first check the source. Pairing details, head-unit settings, and import paths can all affect what you see, so review how power data syncs from Strava before changing thresholds.
When building workouts, keep the target plain. If a set calls for watts, write watts; if it calls for W·kg, name the body-mass value used for that view.
Use watts for interval prescriptions and tests.
Use W·kg for rider or climb comparisons.
Check body mass before trusting W·kg.
Label shared targets with the unit used.
In N+One terms: keep intensity targets in watts, then use W·kg for context.
Keep watts for the work you must hit, and use W·kg for context after body mass is verified.

Switching between km and mi changes the distance labels you read, not the route itself. Your GPS track still describes where the ride went, while the display shows that distance in your chosen unit.
Match N+One to the road signs, head unit, and training notes you use most. That cuts in-ride math and lowers the chance of starting a distance-based effort at the wrong mark.
If a coach or plan uses distance blocks, scan the workout before you ride. For broader setup context, see how weekly plans are built so units match the plan view you expect.
After a switch, open one recent endurance ride and one interval ride. Check splits, lap names, and map labels before you treat the new view as normal.
Match distance units to your head unit.
Check coach notes before starting intervals.
Review one recent ride after switching.
Look at splits, laps, and map labels.

Body mass is the key input behind W·kg. If the stored mass is wrong, the displayed relative power will be wrong even when the power file is clean.
Changing kg to lb should be treated as a display switch plus a verification step. Open Settings → Units, confirm the shown number, then check one ride where W·kg matters.
Keep one body-mass record for the training block you are comparing. If you export files for another tool, use your N+One data export to preserve a clean record of what was stored.
Avoid mixing old and new weight entries in the same comparison. If you changed the number, note the date in your log and compare like with like.
Enter body mass in your chosen unit.
Confirm the converted display looks right.
Check W·kg before hard efforts.
Use one body-mass record per comparison block.
In N+One terms: change the display, not the source record you compare against.
Convert once, check once, then keep the same body-mass source for the block.

Unit settings can also shape how a plan feels when you scan it. A workout that looks clear in km may feel less clear if your head unit is still set to miles.
Before a key block, align N+One, your head unit, and any shared plan notes. If you are moving from another platform, use the platform migration checklist before you judge the new views.
Keep exports steady when you share files or compare them outside N+One. Raw power, time, and route data are easier to check when you do not rewrite old files after a display change.
If a setting seems inconsistent, do not guess through a hard session. Use the N+One support FAQ or review privacy and data settings before changing stored profile fields.
Align N+One with your head unit.
Reload plans after a unit change.
Do not rewrite old exports.
Ask support before editing stored profile fields.
Day 0 — before you switch: Export or snapshot recent key workouts in original units. Note your current body-mass value, threshold power, and distance display setting.
Day 1 — change display units: Go to Settings → Units and choose your preferred display set. Do not edit historic raw exports. Verify that power numbers and timestamps still match a recent ride file.
Day 2 — verify derived metrics: Open a threshold ride and check W·kg plus pace fields. If the numbers look wrong, re-enter body mass in the chosen unit and re-check.
Days 3–7 — ride with the new display: Keep structured interval targets in watts. Use verified W·kg for climbs or rider comparisons, and avoid changing more settings mid-week.
Post-week — reconcile comparisons: When comparing past and new data, use one body-mass unit and recalculate W·kg consistently. Add a short note in your training log about the switch.
To change locale and units in N+One, go to Settings → Units, then pick the display set that matches your riding tools. Keep watts for interval targets, verify body mass before trusting W·kg, and check one recent ride after switching.
No. It changes the displayed distance labels and related views, while the stored route data should remain the same. After switching, open a recent ride and check map labels, splits, and laps.
Use watts for most structured intervals because the target is direct and repeatable. Use W·kg when you compare power relative to body mass, such as climbs or athlete profiles.
Check the body-mass value shown in Settings → Units, then open a ride where W·kg is shown. If W·kg looks wrong, fix body mass first before changing power targets.
Usually no. Keep old exports stable, then note the unit switch in your training log. If you need a shared file, export a fresh copy and label the units clearly.
