Fight Weight Calculator. Reconcile one completed, de-identified combat-sport or wrestling scale record with a comparison limit copied from the exact governing rule or event record.
A quick decision brief for this specific tool
One de-identified completed record and basis; exact governing organization/rule or event source and edition; division/category wording; entered applicable limit/value unit; completed scale source/value/unit; allowance, rounding and procedure context; independent same-record signed difference/value unit
Preserved governing and scale provenance, normalized limit and recorded mass, signed recorded-minus-entered-limit difference, independent difference and computed-minus-independent reconciliation in kilograms and pounds
Validate each source field and token, preserve both source units, normalize pounds with the exact NIST relationship, subtract the entered limit from the completed scale mass, then compare the separately prepared signed result for the identical record
Choose your path
Reconcile one de-identified completed scale record against one comparison limit copied from the exact governing rule or event record and an independent same-record signed difference without deciding class, eligibility, certification, safety or weight-cut action.
Reproduce one completed rule-and-scale comparison without silently using the wrong organization, edition, category or allowance.
Preserve the exact rule source, edition/provision, division wording, entered limit, completed scale record, procedure context and independent signed difference.
Can identify a same-record arithmetic disagreement while interpretation, official scale procedure and eligibility stay with the responsible body.
Check a completed scale summary and an event-record limit that were recorded in different units.
Keep each source unit explicit, document allowance/rounding/apparel/scale context and compare the exact normalized subtraction with an independent result.
Receives traceable kg/lb arithmetic without a universal division table, inferred tolerance or certification verdict.
Understand one historical arithmetic difference without receiving class-selection, body-composition, weight-loss or health advice.
Use a non-identifying record label, copy the responsible rule/event and completed scale records, then inspect the signed result and boundaries.
Can reproduce the calculation while personal identity, diet, hydration, training, performance, medical and emergency decisions remain outside the worksheet.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Reconcile two completed, de-identified scale records with exact kg/lb conversion, source conditions, signed change, and an independent result.
Reconcile two completed, de-identified arm-span and stature records with explicit protocols, units, quality-control context and an independent same-record difference.

Record the organization, document title, edition or effective date, provision, division/category wording and any allowance, rounding, apparel, scale or session context. The worksheet does not infer which rule applies or merge organizations into a universal class table.
Entered limit = value already copied from the responsible current rule or event recordPreserve the units reported by the comparison-limit and completed-scale records. Normalize pounds with the exact NIST relationship, retain kilograms unchanged and expose both source and normalized values. Conversion alone does not validate a scale, procedure, allowance or rule interpretation.
Pounds × 0.45359237 = kilogramsA negative recorded-minus-limit number means the recorded mass is arithmetically below the entered limit, zero means equal and positive means above. Compare that result with a separately prepared same-record difference. None of those signs is an eligibility, certification, safety or medical decision.
Recorded-minus-limit = normalized scale mass − normalized entered limit; reconciliation = computed difference − independent differenceUpdated: August 2026
A reviewer preserves the exact current federation document, category wording and entered limit, then compares it with one completed scale record. The output identifies any arithmetic disagreement while official interpretation and eligibility stay with the responsible body.
An event bulletin records a limit in kilograms while a completed scale summary uses pounds. The worksheet preserves both source units, applies the exact conversion and compares an independently prepared signed difference without deciding the event outcome.
An adult uses a non-identifying record label to reproduce subtraction already performed for a completed weigh-in. The result remains an audit trail and does not recommend a class, body-weight change, diet, hydration or training action.
Weight categories, allowances, rounding, certification and weigh-in procedures belong to the exact organization, event and current rule edition. This worksheet preserves that source context and checks only unit conversion and signed subtraction for one completed record. It does not select a class, certify eligibility, establish a minimum safe or allowable weight, or recommend weight loss, dehydration, nutrition, rehydration, training or medical action.
