What does it do?

The Act (2025 BS, i.e. 1968 AD) establishes metric-system standards for weights and measures throughout Nepal, defining the base units (such as the second, ampere and candela) and the primary, secondary and working standards kept and verified by the department whose Director General is the Controller. A schedule converts old units (tola, dharni, ser, maund, pathi, inch, foot, mile and others) to metric units.यस ऐन (वि.सं. २०२५) ले नेपालभर मेट्रिक पद्धतिमा आधारित नाप र तौलको स्टाण्डर्ड कायम गरी प्रचलनमा ल्याउने व्यवस्था गर्छ; सेकेन्ड, एम्पियर, क्यान्डेला लगायत आधारभूत इकाई परिभाषित गर्छ र विभागका महानिर्देशक (नियन्त्रक) को जिम्मामा रहने प्रमुख, माध्यमिक र कार्यकारी स्टाण्डर्ड तोक्छ। अनुसूचीमा पुराना इकाई (तोला, धार्नी, सेर, मन, पाथी, इन्च, फुट, माइल आदि) लाई मेट्रिक इकाईमा बदल्ने अनुपात दिइएको छ। Nepal Law Commission (lawcommission.gov.np), consolidated official text Preamble; Sections 1–19, pp. 1–14; Schedule, p. 27
Once the Act applies in an area, trade may use only standard weights and measures (unless the government permits otherwise), and contracts and transactions are interpreted in standard units. Traders and businesses must register and obtain a licence from the inspector to use weights, measures and weighing or measuring instruments, which must be stamped; making, repairing or selling instruments requires a licence and model approval (added in 2079). Sealed packages must carry labels stating the net quantity in standard units, and inspectors may open and check suspect packages.ऐन लागू भएको क्षेत्रमा कारोबारमा स्टाण्डर्ड नाप र तौल मात्र प्रयोग गर्न पाइन्छ (सरकारले अन्यथा अनुमति दिएकोबाहेक), र करार तथा कारोबार स्टाण्डर्ड इकाईमा बुझिन्छ। व्यापारी तथा व्यवसायीले नाप–तौल वा नाप्ने–तौलने यन्त्र प्रयोग गर्न दर्ता गरी निरीक्षकबाट अनुमतिपत्र लिनुपर्छ र यन्त्रमा टाँचा लगाउनुपर्छ; यन्त्र बनाउन, मर्मत गर्न वा बेच्न इजाजत र नमूनाको अनुमति (२०७९ मा थपिएको) चाहिन्छ। मोहरबन्द प्याकेजको लेबलमा भित्रको वस्तुको खुद परिमाण स्टाण्डर्ड इकाईमा उल्लेख गर्नुपर्छ, र शंका लागे निरीक्षकले प्याकेज खोलेर जाँच्न सक्छन्। Nepal Law Commission (lawcommission.gov.np), consolidated official text Sections 20–28, pp. 14–20
Inspectors may inspect and seize, and impose fines: for example Rs 1,000–5,000 for using unregistered instruments, Rs 5,000–10,000 for package-labelling breaches, and Rs 5,000–25,000 for giving short or excess measure (Rs 50,000–100,000 for construction materials, gold and silver, petroleum products, LPG cylinders or industries); heavier penalties, including prison, apply to forging stamps and similar offences. Company officers are liable for offences by firms, and cases are prosecuted by the government.निरीक्षकले निरीक्षण गर्न, सामान कब्जा गर्न र जरिवाना गर्न सक्छन्: जस्तै दर्ता नगरी यन्त्र प्रयोग गरे एकदेखि पाँच हजार, प्याकेज लेबलसम्बन्धी उल्लंघनमा पाँचदेखि दश हजार, र घटीबढी नाप–तौल गरेमा पाँचदेखि पच्चीस हजार रुपैयाँ (निर्माण सामग्री, सुन–चाँदी, पेट्रोलियम पदार्थ, एलपीजी सिलिन्डर वा उद्योगमा पचास हजारदेखि एक लाख); टाँचा नक्कली बनाउनेजस्ता कसुरमा कैदसहित थप सजाय हुन्छ। संस्था वा फर्मले गरेको कसुरमा सञ्चालक जिम्मेवार हुन्छन् र मुद्दा सरकारवादी हुन्छ। Nepal Law Commission (lawcommission.gov.np), consolidated official text Sections 28–34, pp. 18–24
