Example 1
- 0.06 g/km
- 500 km
0.03 kg
What NOx at 0.06 g/km and 500 km? 0.03 kg. This is not CO2.
NOx emissions
Type g/km and distance. 0.06 g/km and 500 km give 0.03 kg. 0.08 and 200 give 0.02 kg. 0.05 and 1000 give 0.05 kg. Nitrogen oxides, not carbon dioxide.
This is not CO2. The calculator multiplies g/km by km and divides by 1000. CO2 lives on a separate gold page. Here only NOx in kg.

How it works
NOx emissions in this calculator are grams per kilometre times distance, over 1000. 0.06 × 500 / 1000 = 0.03. The result is 0.03 kg, with a dot and two places. 0.08 × 200 / 1000 = 0.02 kg. 0.05 × 1000 / 1000 = 0.05 kg.
Field a is g/km and field b is km with a metric header. A US header reads g/mi and miles, and the result goes to pounds. The 0.03, 0.02, and 0.05 examples are from g/km and kilometres. There is no L/100 km here.
CO2 on the gold card runs from an intensity and a distance, or from consumption. Another gas, another formula. 0.03 kg NOx at 500 km says nothing about kilograms of CO2 on the same stretch.
0.06 g/km is a homologation or a lab figure you type yourself. The calculator does not guess Euro 6. 500 km is a stretch, not a year. Annual NOx comes only after you type an annual distance in field b.
Type 0.06 and 500, then Calculate. A comma in 0.06 parses. Zero g/km gives 0.00 kg. A sketch from a product, not a tailpipe reading and not a fine.
0.06 and 500 give 0.03 kg. 0.08 and 200 give 0.02 kg. 0.05 and 1000 give 0.05 kg. Another factor at 500 km changes the result.
Formula
kg = g/km × km / 1000
How to use
- Type emissions in g/km, for example 0.06.
- Type distance in km, for example 500.
- Click Calculate. The result is 0.03 kg.
- 0.08 and 200 give 0.02 kg. 0.05 and 1000 give 0.05 kg.
- CO2 lives on the CO2 emissions card. Here only NOx.
0.06 g/km × 500 km = 0.03 kg
kg = g/km × km / 1000. 0.06 and 500 give 0.03 kg. This is not CO2.
- NOx
- Nitrogen oxides. 0.06 g/km and 500 km show 0.03 kg. Not carbon dioxide.
- emissions
- g/km times km. 0.08 and 200 give 0.02 kg. 0.05 and 1000 give 0.05 kg.
- kilograms
- The result unit. 0.03 kg has a dot and two places, as on the page.

Common questions
What NOx at 0.06 g/km and 500 km?
0.03 kg. 0.06 × 500 / 1000 = 0.03. The result has a dot and two places.
What about 0.08 g/km and 200 km?
0.02 kg. 0.08 × 200 / 1000 = 0.02.
What about 0.05 g/km and 1000 km?
0.05 kg. 0.05 × 1000 / 1000 = 0.05.
Is this CO2?
No. Another gas. CO2 lives on a separate card. Here nitrogen oxides in kg.
Where do I get 0.06 g/km?
From homologation or a lab figure. The calculator does not guess a Euro norm.
Is 0.03 kg a fine?
No. A sketch from a product. Not a tailpipe reading and not a penalty.
What if g/km is 0?
0.00 kg. A product with zero.
Does consumption enter the formula?
No. Only g/km and km. L/100 km lives on fuel consumption.
Does a comma in 0.06 work?
Yes. 0.06 and 0,06 both give 0.03 kg at 500 km.
