lb to kg and other weight units

  • 1 lb = 0.45359237 kg exactly — the factor behind every US↔metric curb-weight sheet.
  • Race classes and shipping labels mix lb and kg; convert before you claim a number.
  • Parts catalogs often list grams for fasteners and trim — use the board when a build sheet mixes scales.

US curb weights and trailer tongue ratings usually show pounds. European sheets and many scales use kilograms. This weight converter is for those cross-checks — enter the catalog or scale reading and flip units instantly.

Use it for comparing two cars, converting a parts order, or checking ballast before a weigh-in. Cookie memory keeps your last pair for the next job.

Scale accuracy still matters more than the unit label — convert the number you measured, then verify on a calibrated pad when class weight is on the line.

How to convert automotive weights

  1. Enter the weight you have. Use the figure from the scale, brochure, or parts listing.
  2. Choose lb, kg, or another weight unit. Read the paired result, or tap a board tile to change the right-hand unit.
  3. Cross-check before you ship or weigh-in. Convert both numbers to the same unit before comparing cars or packing lists.
