Tolerable Weekly Intake Calculator
Seven-day bookkeeping of independently authoritative same-basis DAILYreference. Does not derive an authoritative TWI, permit one-day bolus intake or imply acute/chronic toxicological equivalence.
Description
Weekly intake bookkeeping can aggregate seven days of an independently applicable daily reference.
Weekly intake bookkeeping can aggregate seven days of an independently applicable daily reference.1
The aggregate does not establish an authoritative weekly tolerable intake or an interchangeable acute dose.
When to use Tolerable Weekly Intake Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Establish the chemical, exposure route, endpoint, measurement basis and independently applicable assay or assessment reference.
How to use Tolerable Weekly Intake Calculator and understand its results
- Establish the chemical, exposure route, endpoint, measurement basis and independently applicable assay or assessment reference.
- Enter callerAuthoritativelyApplicableDailyIntakeMassPerKg, using the field meanings and rules below, then run the tool.
- Read result.conditionalSameBasisWeeklyIntakeMassPerKg. Use the units and subtraction order below to interpret each value; retain negative differences where returned.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerAuthoritativelyApplicableDailyIntakeMassPerKg | Caller authoritatively applicable daily intake mass per kg | number | Required |
Require a nonnegative independently applicable daily intake reference in the declared units. Multiply by seven for its weekly bookkeeping equivalent. This does not retrieve or establish an authoritative tolerable weekly intake.
weeklyEquivalent=7×callerDailyIntake Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observed calculation or explicit reference | object |
| result.conditionalSameBasisWeeklyIntakeMassPerKg | Seven times the independently applicable daily reference on the same mass basis. | number |

}Limitations and assumptions
Chemical identity, route, assay, exposure basis and reference applicability are caller-established. The output supplies no causal conclusion, universal toxicity threshold or authoritative regulatory determination.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use Tolerable Daily Intake Calculator: A tolerable daily intake is an assessment reference tied to substance, route, endpoint and duration. For a complementary comparison, use Acceptable Daily Intake Calculator: An acceptable daily intake belongs to an applicable substance and long-term assessment context.
