Home fitness unit consistency
Home workouts mix kg, lb, and “plates” by brand. Consistent logging matters more than perfect conversion—pick one display unit and stick to it for trends.
If you change equipment or import a new barbell, re-verify labeled units—assuming “20 kg” plates without checking embossing is a common silent 10% error.
Key takeaways
- Pick grams or pounds for food logs; never mix in one chart.
- Dumbbells: read embossing; gyms mix imports.
- Band tension is not a mass—log assistance separately.
- Deload weeks: keep the same unit so trends stay comparable.
How to convert
70 kg = 154.32371 lb
Barbell plate math
Know whether your gym equipment is labeled in kg or lb per plate; mixed sets exist in garage gyms.
Body weight trends
Weigh at the same time of day and with the same scale unit. Convert for sharing, not for daily noise.
Resistance bands and arbitrary units
Bands often use color levels rather than Newtons—track relative progression within one brand’s chart.
Heart rate and pace
Treadmills may show mph while outdoor runners think min/km—normalize before comparing sessions.
Sharing with a coach
Send both raw numbers and units in one line, e.g., “80 kg × 5 reps,” to avoid ambiguous screenshots.
Calories burned vs weight lifted
Kcal burn estimates mix mass, time, and MET tables—do not back-solve weight from kcal without the model.
Hydration tracking
Bottles may list fl oz while apps expect ml—pick one logging unit for the whole day.
Wearables and unit settings
Sync watch and phone region settings to avoid duplicated steps in different unit systems.
